Altair 60mm Guide Scope Kit Straight Thru Precision LOCKING Focuser (NO EYEPIECE)
The Altair MiniGuider System is based on the very popular Altair 60mm Finder. The package includes a 60mm finder optical tube assembly, a special precision locking focuser for Autoguiders and Webcams, finder rings, universal bracket and stalk.
The new "red trim" version has a variable length tube with heavy duty locking ring allowing more cameras to come to focus.
A good choice for autoguiding with scopes of 1.3m focal length, and more. The product is designed to provide you with a stable guiding optic to attach your guide camera such as Altair GPCAM, Orion Starshoot, or others, without having to use a separate heavy telescope. The package is ideal for astro-imagers who have a wide field portable imaging system. By keeping weight down, you're putting less demand on your mount, making it easier to balance, therefore tracking accuracy is improved. There are no plastic parts to warp, bend or flex.
The precision locking focuser* can be rotated 360° and locked when focused. Once locked, you can remove your camera and re-insert it without losing focus, for faster setup time. 3x Thumbscrews are spaced around the 1.25" barrel, so the camera body will not deflect during guiding. The barrel has a compression ring so that your camera will not be scratched or marred unlike cheaper guide scopes. The 60mm objective has a focal ratio of f3.75 and a focal length of 225mm.
The adjustable tube rings are light, yet more than rigid enough to stay in perfect alignment for autoguiding up to 1.3m focal length. (order product code: MG60-CLAMP for longer focal length imaging around 2 metres focal length or more). The rings cannot twist or rotate like other cheaper makes because the dovetail bar they sit upon has a slight channel to accept their profile. The screws have special tips to avoid scratching the durable high quality and moisture resistant powder coat on the 60mm aluminium optical tube.

This works perfect with the QHY and my ED80. Im getting plenty of guide stars to chose from. Good purchase and good price.

Works well as a straight through finder with a 20mm Plossl, as well as for guiding. Very light but strong. I widened the mounting holes by a couple mm to fit my old C8. Well made with good optics for the price..

Arrived over a week ago just had a chance to get some subs with my HEQ5 and they're great. No problem recommending this product to anyone. Top tip use a 2" dew heater or you'll wonder why you aren't getting focus! Mark

Well made and strong however you need a 1.25" extension for the lodestar to focus, other than that its ideal for any refractor. Particularly like the focuser.

I have this on my 4" triplet and it's a perfect little tube for autoguiding. There are always stars in the field which si quite large. I've had very good service and information from a vendor who know their game.
