60mm F3.6 guidescope with Helical Focuser with Lens diameter: 60mm Adjustable micro-focuser Fully multi-coated doublet Built-in Dew-shield, Rings and Dovetail included Accepts 1.25" eyepieces & accessories High quality all-metal construction Fits Celestron, Skywatcher, Vixen & GSO type saddles A high quality, compact 60mm aperture guide-scope made of metal-alloy that can be used as a guide-scope or as a large aperture finder-scope with standard 1.25" eyepieces.
Internals are painted matt-black to reduce reflections and increase contrast. The built-in dew-shield further reduces reflections and protects the guide-scope's optics from condensation.
It has unusually high maximum focus travel of 34mm, 22mm can be achieved via the guide-scope's retractable tube which is marked in single mm intervals.
The remaining 12mm can be achieved by the guide-scope's high precision non-rotating micro-focuser which also has a sub-millimetre scale to aid re-positioning and accurate focusing.
The non-rotating focuser assembly guarantees that the camera will not turn while focusing which in turn aids framing.
