While this is beyond my kit, what results have you astro dudes captured?

And what kit did you use to get it?

In reply to The Lemming:
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.

In reply to The Lemming:

Lookout on farcebook for 'astrophotography with a 10" dobsonian' gets good results of planetary objects.

In reply to The Lemming:

Contact "andi turner"

Or just do a search of UKC forum posts for astrophotography-related threads upon which andi has posted.

In reply to Blue Straggler: Thanks for the recommendation

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?

In reply to andi turner: Those are some wonderful photos. Thanks for letting us see them

In reply to hindu:

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

In reply to The Lemming:

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.

In reply to hindu: Hey, thanks.

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.

In reply to Marky Mark:

that's brilliant.

In reply to andi turner:

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!

In reply to The Lemming: Used my 10-20mm siggy to get this one - http://www.flickr.com/photos/38420795@N04/8364978089/in/photostream - and my D330s attached to a scope for this one - http://www.flickr.com/photos/38420795@N04/8330777197/in/photostream/

In reply to The Lemming: I use SW200p eq5 with motors and 550d unmodded. just starting really and results show it.... climbing during days, stargazing at night and love it!
