- field of view
Excellent Grab and Go Scope
Pros: Very good optics. Image quality is actually better than an SCT. Has almost the sharpness and contrast of an APO refactor. Very portable and lightweight for a 6" scope. I use it often. Excellent Value 2" Visual back / Quality Diagonal Included 2" EP is better than I expected. (A step above a "stock" EP.) The OTA finish is attractive. Cons: Rather narrow field of view due to the long F/12 focal length. This is the big drawback for me. Balancing the scope can be difficult when using heavy 2" EP or heavy accessories. The finderscope is OK but the straight through design makes it awkward to use. I would recommend as a second scope.
Sky-Watcher 150mm Mak-Cass
Great scope. Performs well mechanically and optically. Cool down period not excessive. Well suited to use on Celestron AVX mount.Made some modifications for ease of use - rotating visual back, two speed focuser, red dot finder. Fits in well with my other equipment aperture ranges. Looking forward to future observing sessions.
