Orion can guide you to better quality astrophotos with our CT80 80mm Refractor StarShoot AutoGuider Package. This affordable autoguiding solution can be added to virtually any astrophotography system to improve guiding accuracy so you get awesome astrophotos every time.

The CT80 80mm Refractor StarShoot AutoGuider Package contains everything you need for precise guiding:

Orion CT80 80mm Compact Refractor Telescope Optical Tube

With a short focal length of 400mm and fast f/5.0 focal ratio, the CT80 refractor makes an ideal guide scope that serves up a myriad of guide stars. The aluminum 1.25" rack-and-pinion focuser has recently been upgraded to eliminate drawtube flexure, which makes guide star acquisition and focusing a breeze.   

Orion StarShoot AutoGuider

The StarShoot AutoGuider's sensor is a high-resolution, 1/2" format 1.3MP CMOS monochrome chip, with 5.2 x 5.2 pixels for highly accurate guiding. The aluminum housing measures just 2.5" x 2.35" and weighs 4.4 oz. Thanks to its small pixel size, the sensor makes the StarShoot AutoGuider a perfect match for the short focal length CT80.  

Orion Guide Scope Rings
The included 105mm ID pair of cast-metal rings are designed to hold the CT80 refractor and provide a wide range of adjustment for alignment with your astrophotography telescope. Each ring features three non-marring nylon alignment screws.

Orion Guide Scope Ring Mounting Bar
The anodized aluminum Guide Scope Ring Mounting Bar attaches the entire AutoGuider Package to an astrophotography telescope. Attach the Guide Scope Rings to the Mounting Bar with the included hardware.

Orion 1.25" Extension Tube
The aluminum 1.25" Orion Eyepiece Extension Tube provides extra focuser "back travel" on the CT80 refractor telescope to achieve focus.

With its total assembled weight of just 3.8 lbs., the Orion CT80 80mm Refractor StarShoot AutoGuider Package won't weigh down your astrophotography set-up.

Not compatible with Schmidt-Cassegrain telescopes without additional hardware.
