‘Observashed’

The new shed is now in place. We started putting it up yesterday and after six hours, a lot of swearing and a few ‘teddies chucked out of prams’ (patience is not one of my strong points; fortunately the neighbours appeared to be out and thus, hopefully, did not hear an ‘f-word-every-other-word’ rant at one stage in the proceedings!) it was just about finished with only a few finishing touches to be added. I did make a couple of cock ups but it seems largely straight, secure and solid so I don’t think it’ll blow down in a gale. It also appears to keep the rain out. There was a thundery downpour this morning and, apart from rain coming in the windows as I hadn’t installed them, it looked to be bone dry with the sole exception of one side which let in a few drops in at floor level. I’ll get some sealant and sort that out. The real test will come when the autumn and winter set in and we get howling gales and driving rain. I am going to leave it for a while before I put my scope in it to see how it fares, that’ll let me see what needs doing to keep any weather out. I went to a party last night and a friend told me that any flat pack assemble-it-yourself item comes with free swear words, the amount of which directly correlates to the nature of the item and the annoyance factor of putting it up; i.e. kitchen units come with 100 free swear words, a shed like mine comes with about 100,000 while a greenhouse comes with several million!
I put the windows in this afternoon, unlike the rest of the thing there were no annoying mini-crises to put up with!

I have not done any serious observing for a while, apart from a couple of mini-sessions with the refractor on a couple of evenings two weeks back. This is because the weather is so highly variable at the moment and evenings which start off clear are not staying that way. We are having a very unsettled summer, apart from a hot couple of weeks in late June/early July. I did manage to sketch a couple of Messiers, just to keep my hand in, while cloud-dodging.

M8, the Lagoon Nebula in Sagittarius. 3.5″ refractor at 36x

M27, the Dumbell Nebula in Vulpecula. 3.5″ refractor at 36x.

I have no idea what these sketches look like on most people’s monitors. My 20″ widescreen monitor went bang just over a week ago so I took it back to PC World (who did not want to know, despite the monitor being well under a year old, so I had to resort to playing the arsey customer which, to be honest, I hate doing. I’ve worked in retail myself – it sucks) and am waiting for the repaired monitor or a replacement. In the meantime I am using an elderly borrowed 17″ square matte flat screen job which isn’t that good for picture editing or viewing. The sketches look appalling on this one, I am hoping that they look a lot better elsewhere!

I also aimed my 400mm Canon telephoto lens at the Moon the other evening – yes, you did read that right. The Moon. Not only that, it meant I was doing some astronomical imaging – the shame. ;-D
Here’s the result of that. I was quite pleased with it, especially as I was handholding the lens at 400 ISO and using a shutter speed of 1/320 sec at f/5.6. I sent a copy to my friend, the well-known author and astro-imager Robert Reeves, who sent me some feedback.
No, I am not going to become an imager, but I do like taking the odd shot now and then. It shows how desperate one can get to do something astronomical!

I have decided that I won’t mess around getting a 16″ Lightbridge. I do want a decent scope of 18 or 20 inches, so I will carry on saving and get a custom-built, quality Dob. One route, and one that I am currently investigating, is to buy an existing Dob chassis and get the optics to fit. I know someone who has a lovely one (a 20″) for sale, minus the optics. However, I’d need an f/3.7 mirror and secondary to fit it as buying a more common f/4 or f/5 would involve a bit of a rebuild, something I don’t want to get into. If I can’t easily get hold of an f/3.7 mirror for a reasonable price (i.e. comparable to that of an f/4) then I’ll probably revert back to Plan A, which is buy a custom-made dob.

From the notebooks 2 – Obscure Planetaries from Australia

Here are some more sketches from that 1997 trip Down Under. These are some of the more obscure planetary nebulae I observed on that trip. All of these sketches were made at the 1997 Queensland Astrofest at Lions Camp Duckadang, Linville, Queensland on 25/26th and 26/27th August 1997. The scope I used was a 20 inch Dobsonian.

Henize 2-111, Centaurus

Henize 2-141, Norma

Henize 2-207, Ara

Longmore 16, Scorpius

Menzel 1 (PK 322-2.1), Norma


Shapley 1 (PK 329+02.1), Norma

 

PK 322-5.1, Triangulum Australe

The observatory is still not up yet. That is because our weather has gone completely to pot and is now more like that of October than it is of mid-July. There are gale-force winds, low temperatures (17C/63F) and rain. Plenty of rain. This will please the miserable buggers who have moaned about the heat and lack of rain and who have now got their own way but I hate this crap and want summer back as soon as possible. Apart from anything else, there’s no observing to be had but even before the weather completely broke up we’d been stuck in a cycle of clear afternoons and cloudy nights for a couple of weeks.

I might have to rethink getting a big scope. I have not yet been able to find a permanent full-time job and the agency work has completely dried up, although I have some part-time seasonal work delivering tourist guides. I have an interview in two weeks’ time for a part-time data-entry job which offers just over £6000 ($9000) and if I get that, which won’t be enough on its own, I could at least combine it with the seasonal work. Unfortunately this seasonal job only lasts for the duration of the holiday season before dropping back to a few hours a week.
A 16″ Meade Lightbridge, at +/- £1800 is not beyond my financial reach on part-time/low wages but a custom-built scope at just over £3100 is, as things stand. Maybe I should just get a LB and then go for a custom-built David Lukehurst Dob when/if my work and financial situation improves? LB’s aren’t bad scopes with a bit of tweaking, although their mirror boxes are incredibly heavy for the size of the scope. Hopefully, though, by the time I have managed to put away £1.8K things might have improved.

From the notebooks – Australia 1997

I was going through old observing note books to scan in my sketches for my new website and I came across some from my observing trip to Australia in 1997. Those brought back some exciting and magical memories! I have decided to share some of the best ones here, as well as in their categories on my web site.
Click each image for a larger view.

NGC 5139, the great Omega Centauri. This ‘King of the Globular Clusters’ can be seen from southern Europe and the southern United States but has to be seen from the Southern Hemisphere in order to appreciate it in its full glory.
I looked at this wherever I went during both trips Downunder, from South America and also each time I have gone far enough south in the Northern Hemisphere to see it.
It’s huge, slightly elliptical and has a curious footprint-shaped area of less star density or obscuring dust, just off-centre. Spectacular.

8″ Cassegrain at 72x, Manly, Brisbane, Qld, Australia
August 11th, 1997

NGC 4755, the Jewel Box cluster in Crux.
This is my favourite star cluster, shaped like a capital ‘A’ and made up of blue and white stars of varying brightnesses but with a conspicuous red giant at the centre.

8″ Celestron SCT, Alice Springs, NT, Australia
July 21st, 1997

NGC 6822, galaxy in Sagittarius. This is Barnard’s Galaxy, a faint dwarf galaxy. The galaxy was a faint elliptical glow, quite faint against the background sky. Elongated 2:1 north-south with no central brightening.

20″ Dobsonian at 60x. Lions Camp Duckadang, Linville, Qld, Australia
August 26th 1997

NGC 55, galaxy in Sculptor.
At -39 S, this is too low to be seen from England, even from the IW (our theoretical cut off is -40 but with atmospheric extinction, not a chance). Huge elongated galaxy with a very bright, mottled core. Only just fits into field of view at 120x.

12.5″ Dall-Kirkham Cassegrain
Ellesmere, Qld, Australia
August 3rd 1997

NGC 7293, the Helix Nebula in Aquarius
I made two separate observations of this. One was from a rural site, the other from an urban one. Needless to say, I saw the nebula without an OIII filter more easily from the countryside than I did with a filter from the suburbs of Brisbane, where it was invisible. It was also 1st quarter Moon when I saw it in the suburbs.
Very large, oval ring with a low surface brightness and diffuse outer edges. No central star seen. Drawing made at the suburban site.

Some sketches from TSP

I have finally got round to scanning in various sketches, as I was doing a rebuild of my website and needed to scan pictures for it. Among these are some of the pics from this year’s Texas Star Party. Click on each sketch for a larger image.

NGC 3245A, Leo Minor
Observed with Dennis Beckley’s 18″ Obsession at 258x.
Very thin and very faint. Pops into view with averted vision. Evenly bright throughout.
Prude Ranch, Ft. Davis, TX, USA

NGC 3279, Leo
18″ Obsession, 258x
Bright, very thin, elongated.
Prude Ranch, Ft. Davis, TX, USA

NGC 3432,Leo Minor
18″ Obsession, 258x
Very thin, irregular. Mottled, elongated centre.
Prude Ranch, Ft. Davis, TX, USA

NGC 5394 and 5395 (Arp 84), Canes Venatici.
48″ Dobsonian
Very large and bright through the 48″. Full of detail. 5395 is the larger of the two galaxies and is interacting with neighbour 5394. There is a bridge connecting the two galaxies. There is distortion in the spiral arms of 5395.
The Lowrey Observatory, Ft. Davis, TX, USA


NGC 3242, Hydra.
48″ Dobsonian, 814x.
This is, like all eye candies, pretty nice in more modest apertures but is absolutely sensational in the eyepiece of ‘Barbarella’. There are two green rings, the inner ring is more oval than the outer one and is thickened at each end while the outer one has a furry appearance. The central star is bright. Between the rings is ‘gauzy’ looking nebulosity which has a tinge of pink to it and the whole p.n. looks three-dimensional. I try not to write ‘wow’ in observing descriptions but…like, um…wow. As they say. Fabulous!
The Lowrey Observatory, Ft. Davis, TX, USA

NGC 4038 and 4039, Corvus
36″ f/5 Obsession Dobsonian, 352x.
Very large and bright at 352x in the 36″.
NGC 4038 is the thinner (uppermost in sketch) of the two galaxies. It is elongated and distorted with a brighter, mottled centre. NGC 4039 is fatter and not so elongated. It has bright HII regions and is very mottled. I can see 4039’s tidal tail easily but 4038’s is fainter and does not show up in the scan, although it is in the original sketch.
Prude Ranch, Ft. Davis, TX, USA

By the way, my website has been added to, with Messier galaxies the first observations up. Click here to visit the site.
I am getting itchy feet and am longing to visit Australia, or somewhere else south of the Equator, to see southern goodies again. Last year’s visit Downunder wasn’t the best for astronomy, although I wasn’t actually on an astronomy trip, with the single opportunity I got for some serious observing washed out by storms and torrential rain during Australia’s wettest and windiest winter for 25 years! However, any potential trips will have to wait until at least the end of 2011 as I want to get that 18″ scope first!

TSP – The Objects: Part 4

Thursday 13th May. This was an attempt at another of Larry’s Lists, this time the ‘Rings Over Texas’ list from 2000. Again, it was Alvin Huey, Dennis Beckley and myself observing with Dennis’ 18 inch. The notes are quite very sparse as I was observing with the others and we were trying to get the list done against interference by clouds and – for ten minutes – by a skunk.

Conditions: Partially clear with some drifting cloud interfering, lightning to the north east.
Location: Prude Ranch, Fort Davis, TX.
NELM: 6.9
Seeing: II-III
Transparency: IV (when the drifting clouds were not in the way)
Instrument: 18 inch f4.5 Obsession dob. 17mm Ethos (121x), 13mm Ethos (158x), 11mm Plossl (187x), 6mm Ethos (343x)

NGC 2685, polar ring galaxy in UMa – Bright, with a elongated centre and an oval outer halo. Nice. 343x

NGC 5122, polar ring galaxy in Virgo – Faint, oval with a brighter centre. 187x.

NGC 2793, ring galaxy in Lynx – Faint and oval. Even brightness. 158x.

AM 1358-221, ring galaxy in Virgo – Quite faint at mag 15.8, oval.

MCG -4-33-27, ring galaxy in Virgo – Brighter than AM 1358-221. Small and oval. Next to a bright star.

Arp 87, NGC 3808, polar ring galaxy in Leo – Double galaxy next to a bright star: one, 3808A is larger than the other (3808B). Quite dim.

NGC 3861, polar ring galaxy in Abell 1367 (Leo) – bright, round, with a brighter centre. This was interrupted by a skunk wandering around; we abandoned the scope for a few minutes until he passed. I’ll get the pun in before anyone else does – we were skunked!

Minkowski 1-64 (PK64+15.1), planetary nebula in Lyra – Round, well defined. Star just off northern edge. 343x.

II Hz 4, ring galaxy in Lynx – Adjacent to a star this is very faint and pops in and out of vision (more out than in!). Round.

NGC 4650A, polar ring galaxy in Centaurus – Elongated. Not very bright.

Mayall’s Object (Arp 148), polar ring galaxy in UMa – Faint, elongated dim glow.

M57, central star – Nearly forgot this one! M57’s central star was on the Rings Over Texas list and we got it without too much difficulty. It popped into view, looking very stellar, during moments of good seeing.

By this time, clouds were beginning to be a real nuisance so we packed up around 3am without observing all 25 objects needed for the pin; we observed around 14 of them although I only wrote down 12. As Alvin and I were going to be back at the 48″ the following night we wouldn’t get a chance to finish the list this TSP.

Alvin and I also managed to knock off the 2010 TSP Binocular Pin. Sat in adjacent chairs with our pairs of binoculars it was a case of ‘yep’ [write down the time]…’yep’ [write down the time]…’yep’ [write down the time]…and so on. Easy and just as much fun as the faint, esoteric stuff in its own way. A bit of light, hit-and-run astronomy.

TSP – The Objects: Part 2

Tuesday 11th May was my second day at TSP, but I didn’t do any observing at the ranch that night as I got invites from Jimi Lowrey and Alvin Huey (who was staying at Jimi’s) to go and observe with them at the 48″. This was far too good an opportunity to pass up and we had an awesome observing session with good transparency and periods of good seeing.
Obviously, using such a vast scope means that faint stuff becomes fair game and we wanted to view some esoteric objects but, of course we couldn’t resist looking at some eye candy as well as the dim and distant.

Conditions: Clear, cool but not cold
NELM: 7.0+
Seeing: around II-IV
Transparency: Excellent, great detail and iridescence in Milky Way when it rose.
Instrument: 48 inch f4 Dobsonian. Eyepieces: Televue Ethos 17mm (287x), Zeiss ZAO-II 10mm (488x), Zeiss ZAO-II 6mm (814x), Zeiss ZAO-II 4mm (1220x).

NGC 3242, planetary nebula in Hydra – We started off with this lovely piece of eye candy. This is, like all eye candies, pretty nice in more modest apertures but is absolutely sensational in the eyepiece of ‘Barbarella’. There are two green rings, the inner ring is more oval than the outer one and is thickened at each end while the outer one has a furry appearance. The central star is bright. Between the rings is ‘gauzy’ looking nebulosity which has a tinge of pink to it and the whole p.n. looks three-dimensional. I try not to write ‘wow’ in observing descriptions but…like, um…wow. As they say. Fabulous! 814x

IC 4277 and IC 4278, galaxies next to NGC 5195 – no description written down.

UGC 9242, galaxy in Bootes – Very flat, edge on. Mottled, with knots visible. Core not bright and the whole thing is fairly evenly bright across. 814x

Arp 84 in Canes Venatici – this is an interacting pair, NGC 5395 and NGC 5394 (the smaller of the two). Nicknamed the ‘Heron’ and it does look like that big water bird, this is very bright and detailed. NGC 5395 is huge in the eyepiece, elongated north-south, with a bright core and spiral arms which are somewhat distorted because of the interaction with 5394.
NGC 5394 is much smaller and is bright, with a slightly brighter centre. A tail of material is trailing from NGC 5394 and a bridge of stars can be seen linking the two galaxies. 814x

Arp 105 and Ambartsumian’s Knot, galaxies in Ursa Major – This is a busy area, with several galaxies and other ‘bits ‘n’ pieces. NGCs 3561 and 3561A are the brightest galaxies in the field, with quite bright MCG+5-27-12 and an anonymous galaxy nearby. A long very, very faint tidal tail stretches off to the north with a very faint knot, VV237f, at the end of it; I could see this some of the time with averted vision and had to look for a long time to be 100% certain it was there (this is on the famous AINTNO list but when we mentioned this to Barbara and Larry the following day at the ranch they were, to say the least, skeptical. Ok, they plain didn’t believe us, which was a shame. 🙁  ).
Ambarsumian’s Knot, VV237b, lies immediately to the south of NGC 3561 and is visible as a faint, slightly elongated smudge of light.

VII Zwicky 466, galaxy in Draco – A ring galaxy, this is small and fairly faint but the ring structure is easily visible. Elongated. Inside the ring, it is evenly bright. The ring is slightly thicker on one side. There are three other galaxies nearby, one of which is edge on. 814x

QSO0957+561 A/B, quasar in Ursa Major – The Double Quasar, visually, isn’t much to look at but knowing what it is, is what makes it exciting to observe. It is a gravitationally-lensed quasar, located 8.7 billion light years away, while the lensing galaxy itself is much closer at 3.7 billion light years.
Both components easily seen, looking like a fuzzy double star, and easily split during moments of good seeing with an obvious gap between them. I could see a hint of fuzziness around the quasar(s) which may, or may not, be the lensing galaxy (this is also on the AINTNO list but, again, we were met with disbelief. 🙁 ) 814x

The three quasars surrounding NGC 3842 in Leo – These are also on the (in)famous AINTNO List and we saw them. Not easily, but they were there. Looking for each in turn they each popped into view during moments of good seeing. Each was a tiny, stellar-looking pinprick of light.

The Jet in M87, in Virgo – Easily seen as a faint ‘pencil’ of light coming from the centre of the galaxy. The orientation of the field of view meant that the jet was located at ‘8 o’clock’ from the nucleus. Another observing ambition realised. 814x

DHW 1-2, planetary nebula in Ophiuchus – Located between two bright stars. Oval, with brightening on one side. Unfiltered, the central star pops into view during moments of good seeing. 488x

NGC 6309, planetary nebula in Ophiuchus – Very bright and blue. Elongated and rectangular. Filaments seen at sides.

Rose 13 (Shakhbazian 19), galaxy group in Coma Berenices – A tight, faint group. Three components seen, one of which was very elongated. A difficult group. 814x.

As well as all the faint stuff, we got blown off the ladder with stunning views of M51, NGC 6543 (the Cat’s Eye Nebula) and M17.

What a fantastic observing session with the giant scope. It’s always a treat to be able to observe with scopes such as this and Larry’s 36 inch, opportunities like this don’t come along often and, when they do, they have to be made the most of and I think we did just that. As much as I love viewing ‘lollipops’ (don’t we all?) I also love looking at faint, difficult objects that few people have ever heard of and even fewer have actually seen visually – that tidal tail from NGC 3561A down to VV237f is a case in point; it would seem that only three people in the whole world have ever visually seen it and that’s myself, Alvin Huey and Jimi Lowrey!

We packed up at dawn and, due to tiredness plus the prospect of walking into the ranch (not a great distance but distinctly unappealing after an all-night sesh), we slept at Jimi’s before returning to the ranch later that morning – and I have to say that Jimi’s sofa is far more comfortable than the Prude bunks!

Finally, a quick note of caution – you have got to be careful when observing at the top of very tall ladders. It is not an experience for those of a nervous disposition and those scared of heights. I am not keen on heights, but I feel it is absolutely worth it for the views you get. However, I am very careful, as it would be easy to drop an eyepiece and hit someone or smash the eyepiece or, worse, to forget where you’re putting your feet and take a tumble. I very nearly did that, when I overbalanced and nearly went ‘a over t’ from the very top of the ladder before just as quickly regaining my balance. A fall would have certainly resulted in broken bones and I very much doubt if my travel insurance would pay out for falling off a ladder while standing at the top of it, on tiptoes, in the dark, looking at a very faint object through a giant telescope.

TSP Day 4 – Thunderheads and the Skunk Nebula

The evening didn’t start out too promising as, during the late afternoon huge thunderheads built up, dominating the eastern and north-eastern sky. At one point, there was one huge and evil-looking cloud that looked unpleasantly like a mushroom cloud, prompting people to make jokes that someone had dropped a nuclear bomb nearby. The effect of late sunlight on the cloud enhanced its hideous appearance and people were pleased when it began to lose its shape. No thunderstorm materialised, although there was some lightning on the horizon.

The skies weren’t too great for observing, although useable, and by three a.m. we decided to pack up for the night which was a shame because we were just on halfway through another of Larry’s Lists, this time the 2000 list ‘Rings Over Texas’. Last night’s observing was a mix of the frustrating (clouds right where you want to look, bad seeing, not being able to find things) and the hilarious – a visitation from a skunk who was on the lookout for dropped food items. Unfortunately the little cutie came far too close for comfort and we spent ten minutes keeping an eye out for him and, at one point, abandoned Dennis’ 18″ and retreated to a safe distance while Mr. Skunk pottered around. He investigated people’s tents and my bag (and I was thinking ‘please don’t spray it, please don’t spray it!’) before wandering off somewhere into the darkness. We had to use dim red torches and averted vision to keep track of the Skunk Nebula but, luckily, he didn’t deploy his chemical warfare on us so the area around us and, more importantly, our possessions remained Eau de Skunk free.

Back to the observing and before being ‘skunked’ (ha ha) by the clouds and deteriorating sky we managed to observe about 14 of the objects on the list:  NGC 2685, NGC 5122, NGC 2793, AM 1358-221,  MCG-4-33-27, Arp 87, NGC 3681, Minkowski 1-64, 2H24, NGC 4650A, the central star in M57 and Mayall’s Object.

I also whipped quickly through the TSP Binocular list and added to my pin collection.

Going to bed at three a.m. at least meant I was able to get up early enough to go birding this morning and I saw some nice species, especially Blue Grosbeaks. I went up to Indian Lodge State Park with Keith Taggart of El Paso, TX and I got some (hopefully good) photos of different species at feeding areas specially set up. Unfortunately Vermilion Flycatchers, a species I’d particularly like to see are still eluding me at present. I am told they’re common but to me that seems they’re common when I am not about. That’s the story of my life when birding!

TSP Day 2 – Aintnos and Ambartsumian’s Knot among others

While observing on Monday night, Jimi Lowrey who is a friend of Alvin’s and who I visited (along with some of the Houston gang) back in 2008 stopped by and invited me to join him and Alvin for a night on the 48″. Obviously this was something not to be missed, especially as there were only going to be three of us – me, Jimi and Alvin – so just after 4pm Tuesday Alvin collected me and we headed up to Jimi’s place at Limpia Crossing.
Just before dinner, Jimi and me headed over to fellow amateur Carl Swicky’s place to see his 32″. In the area, there are other observatories set up and there’s a community of amateur astronomers. With the climate, dark skies, gorgeous birdlife and beautiful scenery I can’t think of a better life, so if ever I win the UK lottery and get the chance to get out of that murky light-polluted place here is where I will come. We looked, admired and took plenty of pics (by the way, pictures will appear here but they might have to wait either until I get back to San Antonio on Sunday or when I get back to England –  I’ve just remembered that the World Cup begins next month, I’m looking forward to that, I love my football – on Thursday next week) including a prime focus capture of me in the 32″ mirror.

After dinner, we headed up to Jimi’s observatory, just up the hill from his house and set up ‘Barbarella’, his giant scope, for the night. The scope is collimated with huge bolts which need a torque wrench to turn and the laser collimater in the eyepiece can only be seen properly with a pair of binoculars!

Once the scope was set up and the mirror fans left to do their work (they suck air in and blow it out of the back of the mirror cell) we went back to the house to get our stuff and some supplies before returning to the observatory.

Fuller descriptions will appear later, but we observed quite a few objects, including NGC 3242 (aka the Ghost of Jupiter), UGC 9492, Arp 84, Arp 105 and Ambartsumian’s Knot – including the Knot itself, the bridge between the galaxies and the streamer that comes away from the bottom galaxy. This latter component is on the famous Aintno List compiled by Barbara Wilson and Larry Mitchell but, sadly, Barbara doesn’t believe us! I think Larry might, but he needs to see it for himself, he says.
Also seen were the ring galaxy VII Zwicky 466, the Double Quasar Q0957+561 A/B (nine billion light years distant, and I saw the very faint galaxy that is the gravitational lens – another Aintno, but we still can’t weedle a certificate out of Larry and Barbara!), the Jet in M87 (a long-standing observing ambition of mine that I hadn’t to date fulfilled, never got round to it. It was surprisingly easy but, then, I was using a 48″ scope), the planetary nebula DHW 1-2, NGC 6304, the compact galaxy group Rose 13, very small and quite tough to seperate the components (I saw 3 members), NGC 5907 and NGC 6543, the Cat’s Eye Nebula. We also saw three more quasars, but I need to find out what they’re called and where they are as I forgot to write them down.
I’ll pad this out with folks and scope photos and object descriptions later – ‘later’ might mean today, it might mean next week, but it will be in the near future.
The transparency was very good although the seeing was mediocre. However, we did get those moments of clarity which allowed quasars, etc, to pop into view. We packed up at 0500 and went back to the house where we all had a few hours’ sleep before Alvin gave me a ride back to the Prude Ranch.
It was an awesome night and to see stuff that’s totally impossible at home with a 12 inch is an opportunity you just can’t refuse. Jimi, I doubt you read this,but if you do – thank you very much indeed for a wonderful night’s observing! To read more about the Lowrey Observatory and Barbarella, Jimi’s 48″ Dob, here’s his website: Lowrey Observatory. By the way, while you’re there, go to the Gallery and the pic on the left side features me at the eyepiece, clinging on for dear life to the colossal ladder, taken in 2008.

Observing 14th April 2010

Conditions:
Seeing II
Transparency III-IV – pretty ‘milky’ with some light scatter
Still, with no wind., although the slightest of breezes sprang up later.
Instrument: 12 inch f5 Dobsonian, 22mm Televue Panoptic (69x), 15mm Televue Plossl (101x), 8mm Televue Radian (190x), Lumicon OIII filter.
As the skies were really murky, and Virgo was washed out by the murk and a lot of light scatter in that direction, I decided to go to Draco for the Herschel 400 objects (and others) there instead. Things were a little awkward as Ursa Major was upside down and the charts difficult to relate to the sky without turning them upside down.
NGC 5866: Bright, fairly small. Elongated n-s, brightens gradually towards a diffuse centre. Bright star on one end and a slightly dimmer star on western edge. Dust lane? 190x
NGC 5907: Very thin, edge-on galaxy. Not much of a nuclear bulge, if any. Fairly faint, elongated n-s, quite large, stretching across field of view at 101x. 69x, 101x
NGC 5985: Very small and bright. Oval. Bright core, elongated n-s. 190x
NGC 5982: Very large oval galaxy, evenly bright, no brightening to middle. Slightly elongated, not face on. Looks like smudge or thumbprint. Very faint, not much brighter than background sky. 190x.
NGC 6543: Very bright and blue planetary nebula, even without the OIII filter. This was fairly easy to find, although at first I thought it would be too low, as the stars I was using to hop to it weren’t that far above the trees in next door’s garden. The OIII filter really brings it out. Small and round. Slightly fuzzy and definitely non-stellar at 69x.
At 190x it is uniformly bright with the middle being no brighter than the surrounding halo. No darkening anywhere within the nebula. 69x, 190x, OIII filter.
NGC 3147: This took a bit of finding, I had to star hop to it, using galaxies, rather than stars. I began with the easy to find M81/82 and went from there. 
Bright, round, with bright nucleus. 190x.

Because of work the next morning, I packed up at midnight BST. For a short session, it was a pretty good one, and I don’t have to return to Draco for any Herschel 400 objects.

Observing April 11th and 12th 2010

At last! A clear night – or was it? It certainly began promisingly enough with the skies clearing off so I set up just before sunset in the hope that I’d get some observing done.
Unfortunately this state of affairs didn’t last long and after the session began drifting clouds appeared and, as if in a devious conspiracy, they sat right where I aimed my scope. It seemed that when I moved to a different part of the sky they followed!
However, despite this, I managed to see the grand total of three objects on my H400 list.
Conditions:
Chilly +4C
Seeing III, Trans IV – Drifting clouds interfereing with observing, plus some high cirrus stuff
NELM 6.0
Instrument: 12 inch f5 Dobsonian; 22mm Televue Panoptic (69x), 15mm Televue Plossl (101x), 8mm Televue Radian (190x), Lumicon OIII filter
NGC 2392 – planetary nebula in Gemini: Easy to find. At 69x it’s round, fuzzy with bright middle. It’s a greenish-blue colour. OIII brings it out well. At 190x it looks very fuzzy with a very bright centre and a dark area between outer parts and centre. 69x, 190x OIII
NGC 2420 – open cluster in Gemini: Nice, fairly small o.c. Very rich and moderately bright. Irregular shape with c. 30 bright stars on a nebulous background which is many many unresolved stars. The brighter stars are all the same, or similar, brightnesses. 69x, 101x
NGC 5194 and NGC 5195 – galaxies in Canes Venatici: Fantastic. NGC 5194 (aka M51) is a large, face-on spiral. Spiral structure is easily seen and it has a big, bright nucleus.
The companion, NGC 5195, is much smaller. Round with a halo surrounding a bright core. 69x, 101x.

At this point, the clouds were becoming more than just an irritation, they were becoming a damned nuisance, so I packed in. As I came back outside to pick up the scope base, the clouds had filled the sky.

The following night, 12th April, wasn’t totally clear, so I didn’t even bother carrying the scope out but, instead, decided to bag Melotte 111, the Coma Star Cluster, with my 8×42 binoculars. Mel 111 is on the AL Binocular Deep Sky list, which, apart from four objects in Cepheus and Lacerta, I have just about finished.
Easily seen with the naked eye, this huge open cluster is pretty spectacular in binoculars. It is harp-shaped, with 15 bright stars outlining the shape of the harp. There are many more fainter stars in among the brighter ones. The stars are all blue-white and the brightest ones all the same magnitude. Nice.
