Key Features
- 102mm Aperture Maksutov-Cassegrain OTA
- 1300mm Focal Length, f/13 Focal Ratio
- Limited-Diffraction Optical System
- Fully Multi-Coated Optics
Similar to their Schmidt cousins, this 102mm f/13 Maksutov-Cassegrain Telescope from Sky-Watcher exchanges the conventional front corrector plate with a convex meniscus lens, which results in a smaller secondary mirror—limiting obstruction and increasing contrast, while eliminating the need for periodic collimation. The Maksutov optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt, but the optical benefits, when coupled with the larger aperture and fully multi-coated optics, make this an ideal scope for solar, lunar, planetary, and deep-sky observation of bright objects like stars and clusters.

question
Do you have the adapater needed to connect the back of the telescope (T thread) to the Celestron f/6.3 Reducer (SCT thread)?
You can adapt the Celestron reducer by using the Blue Fireball SCT Thread Adapter for Maksutov-Cassegrain Telescopes # C-07 which we do not sell. We have never tested a reducer on this telescope so we cannot state the performance will be good.
