The ORION CT80 REFRACTOR STARSHOOT AUTOGUIDER PACKAGE can guide you to better quality astrophotos with our CT80 80mm Refractor StarShoot AutoGuider Package. This refreshingly affordable and incredibly effective autoguiding solution can be added to virtually any astrophotography system to improve guiding accuracy so you get awesome astrophotos every time.

No matter what telescope you’re using for long-exposure astrophotography, precise guiding is an absolute requirement to get pinpoint star images. Using both a dedicated autoguider device and guide scope telescope is arguably the best way to optimize the accuracy of any astrophotography pursuit. Employing a complete autoguiding setup is especially useful when going after images of faint deep-sky objects when multiple lengthy exposures are required.

This complete Orion-exclusive package makes autoguiding easy, and its affordable price is easy on your wallet. The CT80 80mm Refractor StarShoot AutoGuider Package contains everything you need to obtain precise tracking accuracy for your astrophotography setup. Let’s take a closer look at each of the included items:

With a short focal length of 400mm, the included CT80 refractor makes an ideal guide scope. Since the fast f/5.0 optical tube provides an expansive wide field-of-view, this lightweight refractor makes it easy to acquire guide stars. With fully coated optics and a light weight of just 2.25 lbs., the CT80 refractor delivers bright views of potential guide stars and won’t add a lot of weight to astrophotography setups.

The popular Orion StarShoot AutoGuider keeps track of a selected guide star and communicates constantly with connected equatorial telescope mount to correct any tracking errors throughout long exposure astrophotography sessions. The sensor inside the StarShoot AutoGuider is a high-resolution, 1/2″ format 1.3-megapixel CMOS monochrome chip, with 5.2µ x 5.2µ pixels for highly accurate guiding. The chip resides in a super-compact, anodized aluminum housing that measures just 2.5″ wide by 2.35″ long and weighs a mere 4.4 oz. Thanks to the small pixel size, the highly accurate sensor makes the StarShoot AutoGuider a perfect match with the short focal length CT80 80mm Compact Refractor Optical Tube.

The included set of two cast-metal rings are designed to hold the ShortTube 80 refractor and provide a wide range of alignment adjustment so the guide scope can be aligned with your astrophotography telescope easily. Each Guide Scope Ring features three non-marring nylon alignment screws for precise alignment of guide scope without scratching.

The rigid anodized aluminum Guide Scope Ring Mounting Bar is included to attach the entire Awesome AutoGuider Package to an astrophotography telescope. Attach the Guide Scope Rings to the Mounting Bar with the included hardware and then install the CT80 refractor into the Guide Scope Rings. Then couple the entire Awesome AutoGuider package to your astrophotography telescope. Pre-drilled through-holes allow easy attachment.

An anodized, machined aluminum 1.25″ Orion Eyepiece Extension Tube is included for extra focuser “back travel” on the CT80 refractor telescope so focus can be achieved easily.

With its total assembled weight of just 3.8 lbs., the ORION CT80 REFRACTOR STARSHOOT AUTOGUIDER PACKAGE can easily be added to virtually any astrophotography set-up without exceeding your imaging-capable EQ mount’s payload capacity.
