TMB 130SS vs NP-101

Hi all,

I have an opportunity to trade up in aperture from my NP-101 F5.4(great scope, fantastic optics, great for imaging) to a TMB-130SS F7. Has anyone used the TMB? I've heard conflicting views about the optics with respect to thermal stability and quality control issues. I live in the Montreal area and thermal stability would certainly be a factor for me. Any advice would definitely be appreciated. P.S. I am primarily an imager.

cheers,

Jeff

I've heard pretty good things about the TMB. If you are looking for info on the flatness of field, I'd suggest joining the forum at CCDWare. In their CCDInspector forum there is information on dozens of scope/camera combos. I think most of us end up chasing focal length to tighten up images. This would be a nice step up.
