/ Any astrophotography chaps here?
And what kit did you use to get it?
I hooked up a DSLR (it was a 50d but could have been anything, it would have made no difference) to a Galileoscope and got a passable shot of the moon, and a poor shot of Jupiter plus moons,, though enough to see bands.
Lookout on farcebook for 'astrophotography with a 10" dobsonian' gets good results of planetary objects.

Or just do a search of UKC forum posts for astrophotography-related threads upon which andi has posted.
I use all sorts of different kit. When I'm away camping and stuff I use an astrotrac and a dslr with a lens on it. I take long exposures repeatedly of the same patch of sky and then stack the images to reduce noise. Here's one using a 500d and a 200mm f4 lens.
When I'm at home, I use a telescope and a cooled mono ccd camera. these shots can take days to acquire. I use narrowband filters to produce a Hubble palette and this helps eliminate light pollution. exposures are typically 10 minutes plus for each filter. Here's one I made earlier:
You don't need a big telescope, to start with you want a wide lens and dark skies and a sturdy mount. Check out the world at night: http://www.twanight.org/newTWAN/index.asp
Hope that helps a little.
I managed this shot of jupiter and its moons with a 400mm lens and stacked teleconverters (2x and 1.4x) on a crop sensor camera:
Andi- some stunning shots there, makes me want to find some clean sky and have a go!
Assume that your telescope tracks for your long exposures?
Haven't done any photography using telescopes. However, together with my son I have started to take take time lapse photos, including ones of the night sky. This is a very cheap way to get started. All you need is an intervalometer (search Amazon), cost around £20.
After a promising start this was curtailed by the recent run of zero visibility:)
some stunning shots there Andy. I'm just starting my astrophotography joutney. This is a single 30 second exposure of the Orion Nebula through a 150mm newtonian scope with a canon 40D attached with a T ring.
Yeah, I use a guidescope for tracking to keep the mount within 0.1 (normally around 0.03 with good steady skies) of a pixel every half second on average to avoid star trailing.
You can do narrowband imaging from moderately light polluted skies becuase the bandwidth which you're imaging lies outside the bandwidth of sodium and mercury for example, which are common constituents of some street lighting.
I think you've done fantastically well to get that Jupiter shot, really hard using a DSLR, I tend to use a webcam instead.
Sounds easy doesn't it - photos of slow moving objects that are in entirely predictable positions. It was looking at your shots made me realise how much more there was to this astro-phogaphy than that!
I do a few night skies, but not really what you would call astrophotography as I have no scope or specialised kit so can't get fine detail..
This is the sort of thing I can get with a 35mm prime and didymium filter: http://www.ukclimbing.com/images/dbpage.html?id=205865
