Altair 80mm Guide Scope Kit w Precision Locking Focuser and Vixen Bar

Product Description

The Altair Maxi Guider 80 is designed for very accurate guiding, or where you may not have space for an OAG in your imaging setup. As an optical finder scope, it has even more aperture, so you can see fainter objects. In fact this is a mini-telescope giving pleasant rich-field views with a 1.25" eyepiece.

There are no plastic parts in the optical tube and the focuser assembly is all-threaded. This eliminates differential flex in the focuser - a common problem with small telescopes when used as guide scopes. The optical tube and focuser, once locked, cannot move relative to the camera body.

Features:
2.56x more surface area than a 50mm guide scope, and a corresponding increase in brightness.
A 328mm focal length mini-telescope in it's own right, but without the additional weight of a focuser and tube rings.
Machined aluminium tube with super-rigid “set and forget” locking focuser. You will only focus your guide camera once!
Guide Scope Rings, thumbscrew hardware and a 180mm 44.5mm width Vixen/Arca compatible dovetail with 1/4" Photo tripod threads are included.
High contrast due to matte black internal surfaces and a fully multicoated objective lens.
Can be ordered with an optional 23mm Illuminated Reticule eyepiece giving 14x Magnification.
