Deep sky

Because I hand-guide on a ricketty mount, deep sky photography is pretty much limited to widefields, or the brighter, larger deep sky objects.  Suits shooting at 55mm, but occasionally I can zoom up a bit.  Included below is a small sample of some of the types of shots I am able to produce.

Some great deep sky shots by an Australian astrophotographer:

Here's another good Australian gallery:

Pushing it, but here's a  200% re-size.  Happy to get this with just a cheapo zoom lens on an entry-level DSLR!

Milky Way, 5 September 2007 (30-sec subs taken on tripod, Canon 400D)

Andromeda Galaxy, M31, 19 November 2008 (four 2 & 3 minute subs).  Not that great at 55mm and short subs!

NGC3372, NGC3114, IC 2602, 2 January 2008

 NGC 6822 Barnard's Galaxy,
10 October 2010.
This low surface brightness dwarf galaxy is a bit beyond my set-up really, but wanted to give it a try anyway!
 
NGC 55, 1 Feb 2011.  Experiment at guiding with my wobbly set-up at 300mm.  Not really successful.
