"Best deal out there for a high quality astrophotography Newtonian focuser. Very solid and sturdy. "

Superb focuser easily carries my bulky/heavy Maxvision 24mm 82-degree eyepiece and GSO 2" coma corrector perfectly.
Note: the eyepiece screws do not go flush into the focuser as there is not enough travel however its low profile enough, in fact, you will need a 38mm 2" extension for most 1.25" eyepieces when not using a coma corrector.
I thought about 4 stars but it´s so smooth and beautifully finished it´s worth 5! Shipping was fast via DHL, tracking updates very at every change of episode.

"This is a very good upgrade for the UNC with a very robust rack and pinion. I would only prefer a better way to mount an autofocuser. "

"With little bit of mechanical milling work on the base plate it can be adopted to all Skywatcher scopes (at least the ones I have)"
