Well its been almost 2 months since I've done some imaging, and I got a window of opportunity tonight albeit a small one at that. I feel like the only place on earth that doesn't have clouds is in Gary Imm's backyard! Right Gary? :) Anyway, this is just under an hour and half total exposure of "The Ghost of Cassiopeia" before the clouds returned with a vengeance. Need more time with this one and eventually I'll get to it, but for now enjoy this little sneak peek if you will.
