We're about 5 miles from Herstmonceux observatory, and the skies are pretty dark hereabouts Smiley

I love the look of those hot young blue stars (that wasn't supposed to sound naughty), especially the way they flare the spider in the apeture. M42 is the nebula. Sideways, this time, isn't it? Any pictures of the milky way - that looks stunning if away from light pollution.

Ivan, thanks.

Yes those diffraction flares do make it look very star-like even though it is an artifact, the flash appendage on the Cannon fouls the screws on the focusser tube, so I cannot rotate the camera to all orientations. On the raw uncompressed image I think it is just possible to see nebulosity around Merope, the bottom of the bright stars, I can't upload it here though, it's 8 megs or more.I've never had the opportunity to do any long exposures in a dark sky sadly, around here about 30 seconds is the maximum practical exposure before loosing info to the yellow sodium pollution. These 2 pics have had a small amount of levels adjustment to make the background dark again.

They were both 30 seconds at the prime focus of a f4.5 Newtonian, so pretty fast.

Next time I will try piggybacking the camera to see how the Milky Way looks

Tried sticking a 5mm plossl eyepiece in to give about 270 mag, pushing it a bit with the atmosphere all bouncy and slightly murky, but still plenty of light to play with shooting the Moon

Had the telescope outside last night early on and four planets on view - Mercury, Venus, Mars & Jupiter - could see Jupiter's moons clearly - the moon was spectacular - nice to be around if/when Betelgeuse turns into a Supernova.  Smiley

I only looked at the thread as it was top of the 'not read' list... are you guys involved with the Dark Skys' projects around the UK ?  On Friday, I went over to Snowdonia to try to get some dark sky and photograph star trails - a little low cloud and patchy fog forming put pay to that, so ended up on Anglesey Cemlyn Bay - staggering how much light pollution was chucked out by a certain power station a few miles along the coast.  What was more alarming was the two coppers that turned up fully armed in stab jackets determined to mix it up with what was clearly going to be a terrorist setting up a missile launch..... after a few minutes looking and questioning - they left -I was now blind having had torches and headlights in my face for  20 minutes  Smiley
I've not built the star trail image yet - but for this interested in a stills shot:-

Yes, apparently it could go pop any moment, shame an astronomical moment is anything up to a couple of hundred thousand years Sad  not sure if I can wait that long.
Ron, you must have a nice clear horizon to the west where you observe from, I couldn't catch Mercury last night.

I have supported the CFDS run in part by Owen Brazell, they have achieved some good results, but sadly the sky gets more light polluted every year. That's a nice piccy you posted, are we looking at Ursa Major?
