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.

A mighty little guidescope

A well constructed, solid piece of equipment, bought to replace a heavier 70mm scope. Very easy to adjust focus, and tracking improved markedly using the PLL Eaglecore and QHY5.

Testar Guide Scope

A good bit of gear for the Evolux 62 scope, does the job.
Shipping was very quick, very impressed with Testar for quick delivery.

Excellent unit

Received my sample ONE day after I ordered it from Testar! (and I am interstate). Nicely made, well padded box. As soon as the clouds depart, I'll give it a go. If first impressions count, I am impressed.
