Yeah... Summer is a problem over there isn't it! You could wait half of a year, but then it's like -20C or something. I'm not sure.
I tried to search last night. But I went out a little TOO early, and also I had no relative stars so i couldn't focus, cause I came from looking at Saturn. So I wasn't gonna take all that time, and I had to go in anyway...
I actually am going to build an 8" Dobsonian (Newtonian), I think I am needing something more than a 5" Nexstar, and the cheapest 8" around is like $900! No way I am paying for that. So I'll just pay around $100, and take a few weeks!
Btw, what is the aperture of your telescope?
