Wow! An attic observatory? Now that's going to be very sweet! I live in the suburbs and that would be an incredible advantage for star gazing, as trees and houses definitely block some of the sky and the huge comfort factor during the cold winters. Also, congratulations on your recent retirement! I've been retired for 17 and a half years, which seems surreal to me.Cool! My wife works in the Springs, and I used to (retired about 18 months ago) work at a place off GoG. And @mxk116 is near Larkspur, the more the merrier!
I took the 'scope out front so I could catch a few things to the north (house is in the way when I set up on the deck); trees blocked some of the stuff. It's not the cost of the 'scope, it's the cost of adding the attic observatory that's gonna' hurt...
Here's a galaxy (NGC 0891):
