Thought I'd have a poke at the Horsehead nebula over the two clear nights we had. This is 331 x 45 seconds with the GSO 10" F4, overloaded HEQ5 Pro unguided, Baader nebula filter, Pentax K-5 at Rigel Observatory.
Yes I've named it Rigel Observatory, cos my cat Rigel likes to go in for a visit. It's his highlight of the day.
Collimation slipped out a bit so stars are a bit long in the top right.
I think this is my best to date but still some improvements to make. I need more Ha sensitivity so will take some further subs at some stage with a full spectrum DSLR as my K-5 is just a standard unmodified off the shelf DSLR. Imaging during the warm nights with an uncooled camera doesn't help the noise levels either.
