Wow, really nice. I see stuff like that done with obtainable equipment and it makes me want to jump back into observing. I used a lame Meade ETX for a few years & had some fun with it, but it was really limiting. Now, the equipment is so much nicer and much cheaper. I'll probably go with a Meade 8" like this:

My dream is to build an observatory at my place in Montana and stuff it with some very nice astrophotography equipment. I feel like I could definitely spend my last days gazing at the heavens and be completely satisfied with everything
