Mick,
That looks like the very first astrophotograph I ever took. Of the same field!
How do you find the Orion autoguider on the G-11?
I've got my G-11 in full now and am dying to put my 5D Mark II and 200mm f/2.8L II USM lens on it, to capture reflection nebulae and star clusters.
Regards,
Humayun
