TESTAR 30mm f/4 MINI GUIDE SCOPE is backordered and will ship as soon as it is back in stock.
The Testar 30mm Mini Guide Scope has a focal length of 120mm and a focal ratio of f/4. The objective is a fully multi-coated achromatic doublet for a greater optical precision.
The mini dovetail bar can be firmly mounted on any standard finder scope bracket so you do not require any extra piggy back dovetail bar on your telescope. The base of the finder scope includes a 1/4" female thread for a wider compatibility among telescopes.
The focus is achieved by rotating the objective lens that can be locked in position using the red ring.
This scope is compatible with all guiding cameras.
