Opinion on GPS11

Hi everyone- I'm seriously thinking of buying a GPS 11 with XLT coatings. I'd like to know your opinion if you have one of these scopes. I'm particularly interested in the optical quality.

I have a number of friends who own GPS11's and absolutely love them!! Two of the great amateur planetary imagers (Jesús Sánchez and Damian Peach) both use C11's for most of their images and they are as good as they get.

Good luck!!

Hi Gerry,

I bought the aluminum tube version of the Nexstar GPS C11 XLT from Anacortes about 8 weeks and I really am happy with it. The goto and tracking work great. The optical quality appears to be excellent. I need to do some more critical testing to be sure though. But so far, the star mages are just beautiful and the detail on the Moon is awesome. I also saw the crepe ring on Saturn without any problem and a nice sharp cassini division all the way around. So far so good. The only drawback is the weight. It does take a fair effort to carry it around. Almost forgot, the motors are very quiet too! Much better than other scopes i have "heard" in the night.

I was pleasantly suprised that my 11 turned out to be even better (est. ~1/10 wave spherical correction) than my 12" Meade LX200 (~1/8 correction, based on abberator star test). Let me say that the 11 is far easier to handle from a weight and bulk standpoint, must be placement of the handles, and the molded curves because the 10lbs difference alone can't be responsible.
