Shooting the Moon

Just recently I purchased a second lens (a Tamron AF 55-200mm f4.5-5.6 Di II LD) for my Canon EOS 400D. It wasn't until yesterday that I managed to give it a proper test.

Just before bedtime I noticed it was clear and that the Moon was pretty high so I thought it would be interesting to see how large it appears when captured with the new lens attached (previous efforts amply demonstrated that — no surprises here — the Moon doesn't appear very large at 55mm). So I wandered outside, set the lens to 200m and ran off some shots hand-held.

The result isn't actually that bad. If I'm in a position to observe the lunar eclipse next month (during the week, during the early hours of the morning, typical!) it might be worth trying to get a few shots.

Of course, now, I'm wishing for a 300mm lens. ;-)

Floodlighting Petition Response

I just received an email from the UK government's ePetition system to say that there has been a response to the floodlighting petition that I mentioned back in November 2006 (wow, really that long ago?).

You can see the response over here.

Dr Brian Cox

Being a member of The Society for Popular Astronomy, and being interested in photography, it's no surprise that when I attend an SPA event I take a camera with me. I tend to publish many of the images and I've also got an agreement with the editor of Popular Astronomy (the magazine published by the SPA) which lets him use any of the images in the magazine if he thinks they're useful.

The nice thing about this is that I generally don't know which he'll use, if any, so when the magazine turns up it's always a nice surprise to find an image or two in there.

At the last SPA meeting, in October last year, we had Dr Brian Cox giving the main talk (and a cracking talk it was too). I took a handful of photographs, my favourite being this:

Dr Brian Cox #3

So you can imagine how chuffed I was when I sat down last night to read the latest edition of the magazine and found this:

Dr Brian Cox (Published)

Insert smiley face here.

Also, don't forget, the next meeting of the SPA is a week on Saturday.

Comet Holmes Still Naked Eye Object?

Last Saturday I managed to get out for my first "proper" observing session in a while. I had a pretty good night and managed to get views of Mars, M42, Saturn and M81 and M81.

But that wasn't the best part. The best part was the bit when I spotted something odd near Algol:

While stood looking at the Double Cluster with the naked eye I spotted something close by, near Algol, that appeared to be about the same size and of a similar brightness to it. Initially I was confused about what it was. I quickly grabbed my monocular and had a look and could see that it was a faint but noticeable misty patch. Given that I wasn't aware of any object in that location, and given that I couldn't find any such thing on my charts (not that I expected to — I'd have known about such an object if it were a "fixed" item in the sky), I suspected that it was comet Holmes.
Further visual checks at the time and checks with online charts for Holmes suggest that I really was seeing the comet.

This genuinely surprised me. It's been a while since I last observed it and I'd assumed that it wouldn't be visible to the naked eye any more, that it might even have faded beyond a point where I'd be able to observe it with any of my equipment.

Anyone else out there still seeing it this way?

Also, totally aside from the above, I also decided to try something a little different (for me) in terms of astrophotography (not that I do much astrophotography). I took along my Lomo Lubitel 166B, loaded with Ilford FP+ 125, and during the observing session had it pointing at various parts of the sky for around ½ hour at a time. I've no idea what, if anything, I'm going to get out of it, but I needed to use up some frames on the film and the chance to do some astrophotography with a TLR, on black and white medium-format form, was too good to pass up.

Heck, if it turns out reasonably well I might give it a go with colour next time. Might even mount the 166B on the back of the 130M and use its drive to go for some non-trailed shots.

In Support of UK Astronomy #4

This email just in from AuroraWatch:

Dear AuroraWatch subscriber,

You may remember that in spring 2006 we contacted you to raise awareness of damaging funding cuts to the sub-auroral magnetometer network (SAMNET) - the scientific experiment on which the AuroraWatch service depends. We received over 2,500 emails of support which were forwarded to the research council who fund activities in this area. Unquestionably, this had the desired impact as we were able to secure additional funding to keep SAMNET and AuroraWatch running until April 2008. A big "thank you" to everyone who took part! AuroraWatch is alive and well, but alerts are currently quite rare since the Sun is currently at it's lowest point in the 11 year solar cycle.

Having survived a critical period, we were confident that we would secure additional resources to keep the system operating over the coming years (towards solar maximum and more disturbed geomagnetic conditions) and we were expecting a funding announcement before Christmas. Unfortunately, the Science and Technology Facilities Council (the agency who now fund Physics and Astronomy research in the UK) have recently announced an 80 million pound hole in their budget. This surprise announcement is going to result in massive cut-backs to the grants available to universities to carry out astronomy research and the closure of many astronomical and solar-terrestrial physics facilities. Indeed, you may have seen stories in the media about the cuts (typing "STFC funding cuts" into google gives a sample of some of the uproar).

One of the sweeping cuts announced is the withdrawal of support for ground-based facilities for solar-terrestrial physics - the area of astronomy concerned with our planet's connection to the Sun. As a result SAMNET faces closure and along with it, the AuroraWatch service. Other victims include the British ionospheric radars used to study the aurora and the UK's involvement in the Gemini telescopes.

In order to register the tide of anger at these cuts (in part brought about by cost over-runs elsewhere in the council's portfolio), an online petition has been started on the Prime Minister's website. We would encourage AuroraWatch subscribers to visit the site at http://petitions.pm.gov.uk/Physics-Funding/ and support the motion urging "the Prime Minister to reverse the decision to cut vital UK contributions to Particle Physics and Astronomy".

Also, if you are a member of an Astronomy Society, perhaps you could spread the word locally? Petitions with more than 200 signatories have to be responded to by the government. In the first day, the petition attracted over 2,000 signatories so we are guaranteed a response, but imagine how high that number could be if only a fraction of the 25,000 AuroraWatchers added their voice to the protests!

Thanks once again for your continuing support.

In Support of UK Astronomy on Facebook #2

Further to the Facebook application I knocked up, Tim Haynes has created a Save UK Astronomy Facebook group.

If you're on Facebook please think about joining.

In Support of UK Astronomy on Facebook

I'll admit here and now that I know nothing about developing Facebook applications so this is a very quick hack with no bells or whistles.

However, I was thinking it might be nice to have a Save Astronomy "badge" on my Facebook profile, so I quickly knocked up something to do the job. It ends up looking like this:


It's quick, it's dirty, but it works.

If you're on Facebook please considering adding this application to your profile.

In Support of UK Astronomy #3

More on the threat to astronomy in the UK:

Philip Stobbart made the following interesting post on the SPA's BB:

If you want to stick a topical slant on your letter, the Solar Terrestrial Physics community, which carries out observations of the Earth's upper atmosphere that are then used as inputs or validations of climate models are also being cut. In terms of ground based facilities run by the UK, the cut is 100%. In terms of ground based facilities contributed to by the UK, the cut is also 100%, which has sent quite a few of the international radars to the wall. They all run on very finely balanced budgets at the best of times and take decades to fund, design, build and get stuff out of. All done in the middle of the international heliospheric/polar year, which is a two year international research focus on STP.

A letter to the times was sent by one group here.

Results from the facilities to be shut or threatened by this include such minor things as the discovery of the hole in the ozone layer and observations of a part of the atmosphere that is very succeptible to changes in the global climate.
So, let me check that I'm reading this right: On the one hand we've got a government that claims that climate change is a serious issue and that something has to be done about the problem but, on the other hand, that same government is cutting out our country's involvement in producing data that informs the science behind the claims that the planet's climate is changing.

Interesting, don't you think?

In Support of UK Astronomy #2

Further to my earlier post, I've just received an electronic bulletin from the British Astronomical Association and, given that it's got lots of extra handy pointers, I'll reproduce it here (I'm hoping that it's okay to do so — given the nature of the issue I can't imagine that it would be a problem):

Dear BAA Member,

Astronomy is a subject close to my heart and to yours no doubt. You may therefore be alarmed to hear that its future here in the UK is under threat owing to recent announcements by the government. In particular, there have been dramatic developments within the Science and Technology Facilities Council or STFC: the research council that funds astronomy research in the UK. What seems to have happened is a fundamental shift in what the Council and the government see as research priorities, with severe cuts planned in research areas such as Astronomy and Particle Physics.

These cuts will lead to the closure of / withdrawal from a large number of major telescope facilities. In the area of ground-based astronomy, withdrawal from the Isaac Newton Telescope Group on La Palma, and from Gemini South are pretty much decided, but Gemini North, UKIRT, and the Liverpool Telescope in Hawaii are also under threat (we have already pulled out of the Anglo-Australian Telescope). This will be accompanied by cuts in research grants to universities which use these facilities. Likewise, Solar Physics and Space Astronomy will be hit. In short, astronomy research in the UK, currently amongst the best in the world, will really suffer.

All of this came with little warning, and with little consultation with the research community, and at a time when the government is concerned about the number of students taking up science topics in schools and at universities.

PLEASE HELP. A petition has been set up at:

http://petitions.pm.gov.uk/Physics-Funding/

which states, "We the undersigned petition the Prime Minister to reverse the decision to cut vital UK contributions to Particle Physics and Astronomy."

If you wish to offer your support, and have not done so already, you may add your name to this fast-growing petition by going to the above web address and following the directions on signing the petition.

In my view, this is the most serious threat to UK Astronomy in decades and so any help you can offer will be greatly appreciated.

Further to last week's depressing news, Robin Scagell has posted this article on the SPA's BB. The main body, an email he's received from elsewhere, reads:

Dear all,

I forward to you this message from a colleague at UCL, for your urgent attention, apart from what you hopefully may have done about this by other means (like writing to your local MP, which is usually very effective, please also visit www.saveastronomy.co.uk).

There is now an approved (e)-petition online to collect signatures regarding the funding situation for physics and astronomy. Petitions with sufficient number of signees are forwarded to the government who then needs to come back with a response.

Its quick and easy;

Google Sky Map on the Way?

Via Ogle Earth:

Sky Maps coming soon: Being finalized in the Google Maps API Group: Google Sky’s data accessible via the Maps API, ready for embedding in your website.
That's great news (see the demo over here), this is the sort of thing I was hoping would turn up at some point. Google Sky is great and all but the ability to create applications on your own website that make use of their sky map... That could be very interesting.

Finally! Some Solar Action!

As I noted last month the Sun has been very quiet of late (as it turned out I didn't observe a single spot during the whole of November) and I've got used to popping outside with the Solarscope and seeing a totally blank Sun.

So I had a bit of a surprise today when I went out, fully expecting to see nothing, and saw active area 978. It's quite an impressive set of sunspots too. While no individual spot is that large the area itself is one of the bigger ones I've seen for a while.

If you've got a safe method of observing the Sun then get out and have a look. If you don't have a method of doing so, head over here instead.

Depressing

I'm not a "real" astronomer, not by any sensible measure. But I still find this as depressing as hell.

Astronomy is Painless

A little earlier today I was having a wander around RedBubble and I happened upon this t-shirt design. It caught my eye for two reasons: the first was the design, which I thought was rather striking, the second reason was the title.

Wondering what "astronomy is painless" actually meant, I decided to have a proper look and found myself totally bemused by the description given for the idea behind the t-shirt. It seems the general idea of the designer is that we're making a right old mess of this planet (debatable, I know, but let's take that as a given...) and, because of that, we should stop "looking up". Apparently we should stop investigating the universe.

Huh?

Why?

What's the reason?

Well, apparently:

The nearest star (apart from the sun) is about 4.2 light years away, which would take about 90,000 years to get to in Voyager 2. So we’re not getting there anytime soon.
Assuming that year figure is correct (it doesn't really matter), and ignoring the idea of someone travelling "in" Voyager 2, what the hell does that have to do with anything? Really?

Should we only ever observe things we can touch? Should we only ever try and learn more about things we can walk up to and kick? Is turning a blind eye to things that are personally out of reach really a good message to send?

The designer goes on to say:
At present we appear to be destroying this planet, and aware of it, so really that’s a lot like suicide. Priorities people.
Well, you know, he's probably got a point, apart from the "priorities" part. Astronomy and the related sciences are probably one of the few things that can really help people understand and appreciate just how hostile a place the universe is and how unique our little safe zone is. But, because we appear to be messing up in some ways, we should turn our backs on what we can learn and we should suggest that astronomy, of all things, is in opposition to treating our planet in a sensible and sane way?

Sorry, doesn't make any sense to me.

But it's still quite a neat t-shirt.



Edit to add the following a day later:

Well, it seems we're supposed to take it "metaphorically" and that we can take anything from it that we want (dur!). It seems that, having seen the metaphor and having seen that it doesn't seem to quite work, for me, and having tried to engage in debate — something the creator appears to want to spring from their work — it appears that the individual behind that t-shirt is perturbed by the idea of debate and has gone out of their way to acknowledge this by updating the description and changing the title to specifically name me.

That'll teach me for thinking that someone who wants to promote debate wants.... debate.

Bad Astronomical Advertising

Quiet Sun

I've just been catching up on my observing logs and I've just noticed how long it is since I last saw a sunspot.

So far this month I've not seen a single thing on the Sun. Neither did I see anything during the whole of October. Almost all of September was quiet too with the last time I saw a sunspot being September 1st.

You can see from my graphs that this is quite a prolonged quiet spell.

From what I've read solar minimum now seems to be predicted for March next year. Now, okay, I know these things can be ±6 months or so, but it has got me wondering if I'm in for a very quiet winter when it comes to solar observing.

In other news: I managed to get another look at comet Holmes last night.

2007-11-02

You could fill a book... Part III

My short session observing comet Holmes a couple of evenings ago was also another little milestone for me. I finally filled my third log book.

This third book has taken quite a long time to fill. I filled the second one just over a year ago and it took less than a year from me filling the first one.

The main reason for this is that observing has been quite slow this year. While I've done a fair bit of solar observing, evening/night observing sessions have been few and far between. When I got out to observe comet Holmes back on Monday that was the first non-solar session since May!

The reasons are many and varied, but most revolve around weather, some illness and, now and again, a lack of motivation. Something "special" in the sky is always a good motivator and the summer months were totally devoid of anything to observe that was "special" (yes, Jupiter was about, but was so low that you generally couldn't see it from my garden).

Thankfully Holmes has given me that taste again, got me back into that habit.

It was good to have a 'scope out again last night and I think I've finally got that bug back again.

More Comet Holmes

Last night I finally had the chance to get the Antares 905 out and have a quick session observing Comet Holmes.

Much as I expected it was more impressive in the 'scope than it was in the binocular. It was interesting to see how different it looked at different magnifications and how subtle details in the structure of the coma seemed more obvious at one magnification than at another.

The view I had was generally very reminiscent of Tim's photographs of it from a couple or so days back (which remind me a lot of the binocular view I've had), or Joe's amazing sketch of it. However, unlike Joe's sketch, I couldn't see any hint of a tail whatsoever. I do notice that there was a significant different in brightness of the outer ring of the coma on one side when compared to the other and that does seem to correspond with where Joe has drawn the tail he was seeing.

I've not written up my notes yet, I should be doing that in the next day or so.

If you own a binocular, or even a modest telescope, and you've not had them out to look at the comet yet, do so while you've still got the chance. It's a very easy object to find and it's a very rewarding view.
