Altair 60mm Straight Through Finder Scope with an indexed non-rotating, helical micro-focuser.
A 23mm illuminated reticule eyepiece is included with a variable brightness illuminator unit.
Focal length is 262.5mm (F3.75) and the magnification with a 23mm eyepiece is 10x.
The focuser has a 1.25" ID push-fit adapter with brass compression ring, allowing use of 1.25" eyepieces or auto-guiding cameras.
The indexed micro-focuser can be locked, enabling the eyepiece or camera to set at the correct focus-point.
Because the focuser does not rotate, the eyepiece reticule or guide camera is easier to focus and maintain alignment on-target.
The rear of the focuser also includes a T2 thread to allow the addition of extensions.
The finder stalk is compatible with most finder scope brackets on the market, but also includes a universal finder bracket (product code UNIFBR) with a cross-slotted hole pattern to fit most telescopes.
Included in the box:
60mm finder scope optical tube with dewshield and rubber end cap.
Metal Rings with Nylon Tipped Thumbscrews
Metal Finder Stalk (fiits Sky-Watcher, Altair and most finder brackets)
Universal Finder Bracket (two thumbscrews)
1.25" Non-Rotating Helical Focuser (focusing scale, locking thumbscrew & brass compression ring, end cap)
23mm Illuminated Retcule Eyepiece (laser etched reticule)
Eyepiece illuminator unit (variable brightness control)
