Sky-Watcher 127 mm Maksutov-Cassegrain Telescope

This Sky-Watcher 127 mm Maksutov-Cassegrain Telescope is the ultimate portable scope with impressive performance. You could take it anywhere. Although this telescope is relatively small in size, it has optical quality beyond what you might expect from a 5" compact scope. Because it uses the diffraction-limited Maksutov optical system,the Sky-Watcher 127mm produces high resolution, sharp images with high contrast. The optical elements are fully multi-coated to further enhance the image contrast.

With this 127 mm Maksutov Cassegrain Telescope by Sky-Watcher, focusing is accomplished by turning a knob on the rear housing of the scope, which moves the primary mirror slightly to adjust focus. Focusing is smooth and precise.

Questions & Answers

Product Questions

Have 127mm Mak. I note 28mm ep label reads "Coated optics."
Does this mean they are not FMC?
Just got my 127mm. I note 1.25 Celestron visual back screws on
back of this Skywatcher scope. Great, but are threads correct match-hate to cross thread them.
Is there any 1/4-20 thread in the dovetail plate for tripod?
1) What is the OTA weight?
2) Please explain collimation setup-that is I see three collimation screws in back but how can that work with a moveable primary mirror?
