Stars and ships

This weekend (Friday 16th to Tuesday 20th November) I was aboard the Cunard liner Queen Mary 2 for a short cruise to the Channel Islands, France and Belgium. The weather, as has been the norm during 2012, was disgusting but the clouds parted one night and the stars appeared.

I decided to experiment and try to get a shot of Orion with the ship’s forward superstructure and bridge in the foreground. One shot came out and I am quite pleased with it, considering that I was using no tripod, no cable release and I was leaning the camera on one of the spare propeller blades which are kept on the public area of the ship’s bow. Oh and I’d had four pints of Stella Artois by this time, so it’s a miracle even one photo came out (cocktails came later!).

 

Nothing

Nothing whatsoever has happened here. Nothing worth posting about anyway. The weather continues to be mostly shit, apart from the odd few nice hot days here and there. The nights are mostly cloudy, with the few clear ones around a fat Moon. Now we’re nearly into September I am hoping for the usual autumn clear spell but I honestly can’t see it happening, as everything is so wet that any hot sunny spells see a lot of evaporation and yet more cloud. We have had NO clear nights in August this year, we’ve had a few partly clear ones but no totally clear nights. The one night that looked promising was quickly ruined by thick fog.

Good luck to Southampton back in the Premier League (good performance last Sunday at Manchester City, despite ultimately losing) and why are Portsmouth FC still in business?

 

Sky shots

In the complete absence of any observing whatsoever for ages I have been doing other things. Last week I went, with a friend, on a cruise on the P&O ship Oriana from Southampton to Amsterdam and Zeebrugge and back to Southampton and very nice it was too. Except for the rain as we departed and as we arrived home. However, I did manage to get a couple of spectacular sky shots.

My Deep Sky Binocular pin and certificate arrived while I was away. I haven’t got round to thinking about the next project – in fact I am wondering if the sky will ever clear again and why, exactly, I spent £3.5k on an 18″ telescope. Why did I take up such a frustrating hobby? So our latitude means that serious deep sky observing is not really possible between late May and late July but that’s not the point. Shit weather is still shit weather and it’s been going on for bloody months now! Observing is only part of it, I want some decent sunny weather and warm temperatures, something this country *is* capable of providing when it wants to.

More bling on its way

My Deep Sky Binocular award is in the post. I am on a roll! For my next AL project, I now have to decide between Galaxy Groups and Clusters, Planetary Nebulae or Flat Galaxies. Well, I don’t have to do any of them, but it would be nice to get some more pins.

You can now chuck those England flags in the bin after another tournament exit on penalties. England’s participation in penalty shoot-outs always have that air of doom-laden inevitability about them, don’t they? The FA need to take a leaf out of Germany’s book, change the system and rebuild. And practise those bloody penalties.

Spring? Summer? More like Autumn!

British summers have a reputation for being a bit..well…crap. They can often be glorious but, equally, they can be  just rubbish. This spring going into early summer has been utter garbage with, apart from a nine-day spell of glorious sunshine and 86°F temperatures, two MONTHS of rain, gales and more rain. This is utter crap even by our usual fairly low standards, but the south coast doesn’t usually get months on end of rubbish weather, this is usually the preserve of Scotland.

Part of the reason, apart from Atlantic lows coming in from the west is the jet stream which should be over the north of Scotland right now but, instead, is lying over the south of England. This is about the third or fourth straight year it’s done this and it’s getting old now. I have said for a long time I want to emigrate but now, if I could afford it and had a job to go to, I would go tomorrow as this is one crap summer too far!

It is admittedly academic, given that there are no real dark skies until the middle to end of July, but so far this June we have not had a single clear night…NOT ONE! I may not be observing at this time of year but I want high temperatures and sunshine, not wind and rain! Apart from that 9-day nice spell May was nearly as bad but we did actually muster up 14 clear nights out of 31. I was away for half of April but that was very poor from the information I was given. If it’s any consolation it’s the same situation on the Continent and, Down Under, conditions are also miserable (but not surprising as it’s coming into their winter).

What do we want? SUMMER! When do we want it? NOW!

Finally, and on a totally unrelated but more cheerful note, with the Queen’s Jubilee recently and other exciting British things coming up during the rest of the summer (I use the term summer loosely, given the current diabolical conditions), here’s a patriotic tune to tap toes to, the Grenadier Guards’ marching tune.

 

Oh and good luck England in their final Euro 2012 group game on Tuesday – and beyond…

Some sky shots

I am not, and don’t intend to be, a serious imager. But I couldn’t resist popping off a few photos last Monday, with my Canon 7D and 18-135 EF-S and 70-200 f/4 L lenses.

Just two weeks to TSP and 1½ weeks until I head over to Texas …how time flies – I booked my flight six months ago and it doesn’t seem that long. I’m doing talks at San Antonio Astronomical Association and at TSP itself.

Clusters in Moonlight, 7th October 2011

Date: 7th October 2011
Conditions: 84% illuminated Moon, chilly, breezy. A few high clouds and a halo around the Moon.
Seeing: Good to average
Transparency: Average to poor
NELM: 5.5 to 5.2 later (because of Moon)

The Moon is nearly full but I decided to have a quick observing session anyway. However, I left the 18 inch tucked up in the shed and used the little 8 inch Celestron Newtonian instead, as I decided it wasn’t worth getting the big one out in such poor conditions plus it was quite windy, which would have meant the big scope would be awkward to use.

The session began late as I was waiting for thick cloud cover to clear, which it eventually did. I decided to observe some open clusters, because of the Moonlight and decidedly poor transparency. There was no point in going after galaxies or faint planetary nebulae in those conditions.

NGC 7129, open cluster in Cepheus – A very small but obvious cluster next to NGC 7142. Bright and obvious T-shape, despite its small size. Compact. There are six bright stars made up of three doubles, including a very wide one, and several fainter stars among the six. However, the cluster is mostly washed out by the Moon. There is nebulosity with this cluster, which I would probably see on a Moonless, more transparent night, but I didn’t see it with either UHC or OIII filters. Fits into the field of view at 73x. 8 inch f/4 Newtonian, 36x, 73x

NGC 7142, open cluster in Cepheus – The neighbour of NGC 7129, this is much larger and richer. Detached. The Moon is washing out the sky but I can count 11 brighter stars and about a dozen fainter ones. The rest are washed out. Fits into the field of view at 53x. 8 inch f/4 Newtonian, 36x, 53x

NGC 7380, open cluster in Cepheus – A rich, triangular cluster. With averted vision, I can see a hazy background, indicating many more stars. The cluster is at the end of a distinct curved line of three stars (the middle one of which is a double). At 73x I can count 20 stars but more remain unresolved. The nebulosity with the cluster was not seen with any filter.  8 inch f/4 Newtonian, 36x, 73x

NGC 7510, open cluster in Cepheus – This one took an age to locate, mostly because I was using a small Newtonian on an equatorial mount and performing contortions to look through the Telrad finder! It is small, compact and bright with a wedge shape. It is rich and very concentrated. At 36x, I could see individual stars.
A nice view at 73x with about a dozen stars resolved, plus quite a few more fainter ones in the background. With averted vision there are plenty more stars in the background. A very nice object. 8 inch f/4 Newtonian, 36x, 73x

NGC 1513, open cluster in Perseus – A faint oval patch of stars which is mostly obliterated by the Moon. I could see several members but the rest remained as a misty patch. 8 inch f/4 Newtonian, 36x, 73x

NGC 1444, open cluster in Perseus – A pretty boring object as it is just a nondescript gathering of stars around a bright multiple. 8 inch f/4 Newtonian, 36x, 73x

Packed up at 0100.

I am typing this while listening to the post mortem of yet another fail from an England sports team in a World Cup. This time, it was the Rugby Union side who let the country down, in the form of an atrocious capitulation to France. The team, with the sole exception of two decent wins in the group stages against Georgia and Romania, have been pretty awful, narrowly avoiding defeats against Argentina and Scotland. Typically the French, who have been equally awful in their group stages as well as mutinous, as only the French can be, decided to up their game against England. But, that doesn’t alter the fact that England were enfoncer la merde as the French might say. That said, I hope the French go on to beat Wales in the semis. I do NOT want to see Wales in the final…I’ve got Welsh friends and I don’t think I could stand the gloating!

Visit to Cambridge

I was asked to do a talk at the Webb Deep Sky Society’s AGM, about my ‘Experiences at the Texas Star Party’. The meeting was originally scheduled for December 2010 but, thanks to deep snow and dangerous travelling conditions, it was postponed until 18th June 2011.
I arranged to travel up with Don Miles, who met me at Portsmouth’s Wightlink Gunwharf Terminal. It was an early start, as Cambridge is a three hour drive, at least, from the South Coast. After an uneventful drive up, with a brief stop at Clacket Lane Services, we arrived at Cambridge University’s Institute of Astronomy at 0930. I hadn’t been to the Webb Society annual meeting since 2005, when it was held at the Atomic Weapons Establishment at Aldermaston, simply because of the awkwardness of getting to Cambridge, where it’s been held ever since, and back in a day from the Isle of Wight. It’s the Solent crossing that makes life difficult, more than anything, as it adds at least an hour to travel times and in the late evening, if you miss one ferry there isn’t another for two or three hours. I left home at 0430 on Saturday morning and didn’t get back until 0300 this morning, but despite the negatives of the location from a logistical point of view, the IoA is a lovely venue and has plenty of astronomical interest – not least the historic telescopes in the grounds and spectacular posters of galaxies, planets, nebulae and clusters lining the walls of the Hoyle Building.

The meeting was held in the IoA’s Hoyle Building

After coffee and chat with people I hadn’t seen in ages, it was time for the meeting to get under way. My talk wasn’t until the afternoon, scheduled that way in case of any problems getting to Cambridge. The talks were Wolfgang Steinicke – The M51 Mystery: Rosse, Robinson, South and the Astonishing Detection in 1845 of Spiral Structure; Robert Kennicutt – The (Very…) Improbable Universe; Mark Hurn –  Star Atlases; Martin Griffiths – New Developments in  Planetary Nebula Research; Andrew Robertson – Telescopes and their Capabilities; then me with Experiences at the Texas Star Party and finally David Ratledge – New Developments in Astrophotography.
Of the talks, my particular favourites were Wolfgang and Andrew. Martin was also very good. Andrew’s talk was right up my street, with plenty of pictures of large dobs and his sketches, as he is purely a visual observer but I will disagree with his assertion that we visual observers are a dying breed, though! Andrew is a member of Norwich Astronomical Society and they sound like a very active club with a thriving deep sky observing section. Not only that, they mostly have large dobs of between 16 to 24 inches, with one person with a ‘minnow’ (my description) 14 incher – a few years ago I wouldn’t have described a 14″ scope as a ‘minnow’, such is the rapid pace of telescope development – and are among the most active and keenest deep sky observers in the UK. As a committee member of a local society struggling to get our own membership off of its collective arse and out observing, it sounds perfect to me and made me wish I lived in Norfolk – I’m envious! Later, in conversation, Andrew claimed to me that Norfolk has better skies than the Isle of Wight. They’re probably a bit drier (depending on the season, our problem here on the island is often sea fog which wipes out the southern horizon as seen from the southern coast) but I doubt they’re darker although it does depend on local conditions at any given time.
My own talk went well, I was more fluent than I thought I would be but when you’re speaking to like-minded people it’s easy. Certainly easier than practising the talk on uninterested relatives and bewildered pets! I even managed to get laughs with stories about skunks and hazards.

I got outside and walked round the grounds at lunchtime. I joined a group having a look round the telescopes but we only had time to see the 12″ Northumberland refractor before having to go back inside for the afternoon session.
Here are some photos of the grounds and domes (excuse the poor photos, I was using my Samsung compact whose image quality is not the best).

There were a few vendors at the meeting, among them Cambridge University Press, Green Witch, a secondhand book dealer (who lost a potential customer when he said ‘Faith, Hope and Charity’ on learning my name. It may sound trivial and an overreaction but it is guaranteed to piss me off every time someone says it, especially when you’ve heard it for what seems like 54 billion times since early childhood! Don’t do it, it’s old, boring, unoriginal and insulting. How would people like it if I made fun of their name? ‘Scuse the rant!) and the Webb Deep Sky Society themselves.
I was tempted by Wolfgang’s book Observing and Cataloguing Nebulae and Star Clusters but was put off by the retail price of £90. The ‘show special’ was £72 but that was still very expensive so I will wait until I have a bit more disposable income. I am also probably going to get Philip S Harrington’s Cosmic Challenge at some point as it looks like an excellent book.
I did, however, buy the Webb Archive DVD which has scanned copies of every Quarterly Journal and Deep Sky Observer since 1968. It also contains the Observing Section Reports. As for the OSRs, I have quite a few back copies of these but when I saw the IoA was offloading two bound volumes of them for a fiver, as part of a clearout of the Library, I couldn’t resist them and snapped them up before anyone else could, so they’re now sitting happy and loved on my bookshelf. The Library was also getting rid of the Millennium Star Atlas for whatever offer you made but, as it wasn’t just the Millennium Star Atlas but the entire Hipparchos Catalogue, I decided against it. Despite being sorely tempted, there’s no way I could have carried that lot on and off the ferry!
Something else that came out of the meeting was me agreeing to revise and update An Introduction to Visual Deep Sky Observing. I wrote the original in 1998 and a lot of it is now dated and in bad need of revision. I plan to rewrite a lot of it, plus add more content, including more sketches and photos. I also have another Webb book project (as editor, rather than author) in the planning stages, of which more nearer the time.

When the meeting finished and we’d packed up, the committee and speakers headed for a local pub in Girton for a meal and chat, eventually going our separate ways at 2130. Don and I headed back to Portsmouth, timing it so I didn’t have a long wait at Gunwharf. After a mercifully brief wait (it was raining, the Wightlink waiting room smelled bad and there was a tramp asleep on the seats inside! I don’t want to be rude but I don’t think the tramp and the smell were unconnected!), I got the 0130 ferry home across a stormy Solent, collected my car from Fishbourne ferry terminal and got home just before 3 am.

It was an enjoyable day and it was good to catch up with people I hadn’t seen for a while. Out of the people I have known for years I’d only seen Owen Brazell since 2005, at the Isle of Wight Star Party, and this May’s VAS monthly meeting when he was the speaker. I would like to go next year, but I will definitely have to sort out more sensible travel arrangements because leaving home at 0430 one morning and not getting home until 0300 the following morning is just stupid. Next year, I will see if I can stay with my sister in Newbury for a couple of nights and go from there, rather than a round trip crammed into 24 hours.
Many thanks to Don for the lift up to and back to Cambridge from Portsmouth. It was a pleasant trip, where we talked about astronomy, life in general and cricket, of which I am also a fan. Don’s involved with women’s cricket, as photographer, selector and chairman of Sussex Women’s Cricket Association. I am more of a fan of the men’s game, especially Hampshire and England, but it was interesting hearing about the women’s game.

After my blog post about how the UK weather isn’t quite as bad as often perceived, it’s done nothing but rain and blow a gale since early June and May was also fairly unsettled. I think we can blame Owen for this, as he’s bought a 22 inch Obsession UC! Oh well, summer is yet young and June is often unsettled – and is probably the best month to have rotten weather as it’s not much use for observing thanks to the twilight!

You what?

*I had made a post under this title yesterday, but I accidentally deleted it when trying to delete something else! So here it is again, or what I can remember of it*

Being less than mobile recently, thanks to a knee injury, I have been doing a bit more reading than usual. I have been looking through my collection of Deep Sky Magazine and an article by Jeffrey Corder in DSM #6 Spring 1984, titled ‘Observing Low Surface Brightness Objects’, contained a sentence that caught my eye. The sentence in question read: “The reason old Reverend Webb described M33 as “Large, faint, and ill-defined” was more because his notoriously damp homeland of England is a generally poor site than because M33 is especially difficult“.
Er, “…generally poor site”? That’s a sweeping statement if ever I saw one and, like all sweeping statements, is actually not entirely true. Okay, England isn’t great, but neither is it a ‘generally poor site’ and, apart from the north-west, a lot of it isn’t ‘notoriously damp’ either, especially in the south.
Arizona is ‘great’, West Texas is ‘great’ (when it isn’t on fire), the outback of Australia is ‘great’, Chile’s Atacama Desert is ‘great’ and so on, but most observers – most people – don’t live in these observational nirvanas, they live in areas that are as cloudy and as light polluted as England, so it does kind of annoy me when I hear and read remarks such as Jeffrey’s and ‘Soggy little Britain’, which an American friend said to me on Facebook recently.

I used to be under the impression that people in the US, especially, had pristine home skies and spent all their spare evenings observing, so I was a little jealous! My visits to the Texas Star Party, and also reading forums such as Cloudy Nights, actually proved otherwise as most people live in areas which are cloudy and/or light polluted. People have to live in or near towns and cities for work, unless they happen to be rich or retired, and really only get dark sky observing opportunities around new Moon if the weather co-operates and they can get out of town for a night or two.

While 300+ clear nights a year would be nice, we don’t do too badly here, with over 100 nights a year, give or take a few, that are observationally usable – if we ignore the Moon’s phase – most particularly here on the South Coast where high sunshine levels translate into a decent amount of clear nights. I’ve been keeping a record of nights that are usuable for observing (partly clear as well as 100% clear) and, so far, in 2011, we’ve had 69 nights out of 155 that have been clear or partly clear, despite the coldest and cloudiest winter for 40 years. That’s 44%, not too shabby for a ‘generally poor site’. Out of those 69 nights, 52 have been totally clear. 2010 was 46% clear or partly clear (33% totally clear). Anything less than 50% clear goes down as cloudy! 50% clear is usable and I often observe on partly clear nights, as long as the Moon isn’t in the way. I have to admit that even I don’t observe as much as I could, as it isn’t always possible, particularly in the summer when nights are very short and in mid-winter when sub-zero temperatures make it a test of endurance, and at the age of 41 I’m beginning to find that several nights in a row is hard going, particularly when I am also working during the day.

That said, the weather does have a habit of being inclement when there’s an astronomical event on. Planning a public session to view an eclipse? You can bet it will probably be cloudy! However, the same goes for the USA, outside the dry and clear south west, and other countries, too. If you plan your observing around weekends because of work, particular dates or events, then there is a risk it will be cloudy or wet, as such a narrow window of opportunity means the perspective will be skewed. It doesn’t mean that it’s always or even mostly cloudy and wet.
Even the Texas Star Party this year wasn’t an observational success, as they were clouded out for all except two-and-a-half nights. Nearby range fires, caused by lighting strikes, haven’t helped either. A few past TSPs have been a bit hit-and-miss, too with 1992, 2005 and 2007 being pretty bad.

It’s a bit of a ramble but what I am trying to say here is that people tend to criticise England (and Britain in general) rather unfairly, when the truth isn’t as bad and it does annoy me, particularly when it often comes from people who are no better off than we are. It’s true that we British do love to complain about the weather but as whingeing is a national pastime here (and, yes, I can moan with the best of ’em!), that doesn’t mean much, as sunshine and 90 degree temperatures here bring as many complaints from people as any other type of weather! In short, while we don’t have the best observing conditions here by no means do we have the worst either. England is probably about average in the grand scheme of things.

Light pollution is more of a menace than clouds. The UK, especially England, is overcrowded and, as such, is quite badly light polluted and we have a big problem here in that respect. Public ignorance is a major factor in this as they tend to think that turning night into day is somehow a ‘good thing’ and prevents crime. It isn’t and doesn’t. It’s wasteful, adds to carbon emissions and isn’t proven to reduce crime – and criminals need light to see, they don’t have superior night vision compared to the rest of us!
Local council street light switch-offs, due to austerity measures, have been greated with bleating about ‘blackouts’ and claims of increased crime (although that’s not supported by facts) and one woman in Northamptonshire claimed she fell over in the dark and injured herself. You don’t just ‘fall over’ in the dark unless you’re not taking adequate care and using a torch, unless you have a problem. It’s the same with pedestrians walking along unlit roads at night – if they wear light or reflective clothing then they have far less chance of being run over, unless they do something really stupid.

The battle against light pollution is slowly gaining some ground with a lot of councils, including the Isle of Wight, beginning to put new LED lamps in. Apparently, these shine downwards and little or no light actually goes into the sky. I have read reports where amateur astronomers in areas where these have already been installed say that there is a big improvement. It’s a step in the right direction and, if these lights shine where they are supposed to but the sky remains dark, then everyone will be happy. Light trespass is now an offence, so badly shielded and directed security lights have to be adjusted if a complaint is made.

Returning to Jeffrey Corder’s article, as for M33 itself from here it’s certainly large but it’s not a hard object to see. It’s a naked-eye object on a good night from here and is not that faint or ill-defined, being a nice sight in binoculars. Telescopically there’s lots to see such as HII areas and, with a large enough scope, globular clusters.
Rev. Webb’s impression of it was more likely down to the quality – or lack of it – of his scopes rather than any shortcomings in the quality of his sky. I daresay that telescopes back in 1984 were superior to those of the 1800s, which was Webb’s era.

The sky is clearing, the good weather is returning…

…and I can’t observe thanks to having done some damage to my left knee. It got twisted round at an unnatural angle yesterday morning and I felt something snap inside accompanied by an excruciating pain at the same time. I decided to ignore it in the hope it was nothing serious only for it to get worse and keep me awake last night. So, it was off to A&E this morning for them to take a look. I was in there four hours and, out of that four hours, I was actually only being seen by a member of staff for a grand total of about 10 minutes.
Anyway, when I eventually got seen, they X-rayed it, proclaimed it to be a possible ligament or cartilage tear and sent me on my way with crutches (which have to be the work of diabolical forces, I hate crutches), instructions to keep the knee up and an appointment to see a specialist next week.
This week has not got off to a brilliant start, I already have a slight bad case of the ‘I wish I was somewhere else, that somewhere being the TSP‘ blooz and now this. It also means I can’t work this week and no work means no pay. Anyway, I’ll keep off it for a few days and see what happens.
Still, it’s probably the best time of year to do yourself a mischief – nights are too light for any serious observing, and I was only planning to do some sketching of the brighter Messiers and DSOs anyway. Knee damage definitely rules out using the big scope but I can probably still do something with my little scopes and binoculars. Small scopes can go in bags, although I don’t know what can be done about carrying my tripod outside…I must have a spare camera strap somewhere.

While feeling sorry for myself this afternoon, I browsed through some of the astronomy stuff I have gleaned from the net and other sources. There’s plenty of material for observing projects when I want a change from the Herschel 2500. I’ve downloaded some of the TSP observing lists and I already have Larry Mitchell’s Advanced Observing Lists on computer and in a paper file I brought home in 2008. I am getting an 18″ f/4.5 dobsonian from David Lukehurst, thanks to a tax rebate a couple of months ago (that paid half the cost and my aunt is lending me the other half), so I have a good chance of doing Larry’s lists, apart from the stuff that’s too far south to be easily seen from here. An interesting project would be to sketch each of the objects on the ‘easier’ lists. Ok, I won’t get an ‘observing pin’ for it, as the lists have to be completed in situ at the TSP, but it’ll be a fun project to do.
The dob, by the way, should be completed by the end of July, just in time for the return of the dark skies after mid-summer. Like most deep sky observers, I have always wanted a big scope >16 inches. Life got in the way of me getting one last year, as the savings I had needed to be spent on something else but the chance came round again, thanks to the tax refund and my aunt lending me money, and I took it.
