Re: Petition to Introduce legislation to combat light pollut

No dedication - on many occassion I've observed all night long in mid winter with thick ice on the scope. On one occassion I fell asleep at the eyepiece when it was several degrees below and my eyebrow stuck to the eyepiece! Fortunately I woke quickly, probably falling off the stool and thought, 'be...

Petition to Introduce legislation to combat light pollution

There is currently a petition running on the UK government petitions web site to intoduce legislation to combat light pollution. It currently has only 2,950 signatures and only has 2 months left to run. It needs 10,000 signatures for a government response. I urge all SPA members to sign it. If we ca...

Marl - earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions.

So more evidence of running water on Mars.

Had about 3 views of Orion in the early hours over the last week (been getting up about 3am to observe Jupiter and staying through until 5.30am) and thought, 'that's come around quick - winter's on the way!' By 5am-ish there are 3 'red' stars prominent in the ESE to ENE; Betelguese, Aldebaran and fi...

Had a brief view under very dark skies last night before cloud rolled in. At x180 in the 12" D-K the coma had a grannular texture to it. Still no tail, ditto with the Lumicon comet filter which helps you see ionized tails, still nothing just dimmed the view. Could see it (just) in my 11x70 finder bu...

I've observed it a couple of times now, once a few weeks ago and this Sunday night just gone. It was very prominent in my 12" D-K at x162 with a bright core displaced from the centre of a diffuse outer halo - hard to define where it ended. I couldn't detect any tail. I do have a comet filter which w...

Nice sketch Peter. I've had about 3 visuals on Jupiter in the last couple of weeks but the seeing has been so poor due to it's low altitude I haven't even contemplated a sketch. Could you forward me your observation report please?

Talking about cloud cover for this year I have noticed there has only been a few clear nights to Observe this year-you could probably count them on the fingers of both hands-there seem to have been a lot of cloud cover for 2010-is it increasing over the years because 2009 was just as bad? I agree, ...

Well I played it cool, setting my alarm for 6.30am knowing I had a good view down to the horizon in the NW from my landing window. I didn't look out until 6.40 am having first got a cup of tea and was surprised to actually see it (used to British weather killing these events) with a substantial 'bit...

Dear Robin Yes, Martin's Mars video is excellent ! If I had to name my favourite planet (excluding Earth !); not an easy decision but I think I'd say Mars. Although I do enjoy seeing close up space probe images of the planets, but for me the space probe images sadly destroy something of a planet's ...

Interesting technique. Regards, Andrew Dear Andrew, In fact last year I noted with 18x50 IS binoculars that only one main belt was visible. I confirmed this by handholding 3x opera glasses behind the binoculars, also handheld but touching the window. A lot of false colour as lining things up perfect...

Spotting Scopes

Talking of spotting scopes, have a look at Cliff Meredith's observation of Jupiter using a £25 one from Aldi which I've just posted on the SPA web site:

Hi Graham, The suppression pads work well if the tripod is on a solid concrete base but I never used them on soft ground - better to 'spike' the tripod leg into the ground. I suppose it depends how rigid and solid the decking is - I suspect it could make it worse by setting up resonanses. Doesn't re...

Totally agree. Went out about 11pm wed for an observing stint - as soon as I walked out of the door these two caught my eye and I just stood looking at them for about 5 mins - glorious sight.
