Starlight Xpress Costar Autoguider

The CoStar is a low cost Cmos imager/ Autoguider.

It features a sensitive Mono CMOS sensor with 1304x1024 Pixels with a USB 2 INterface and Opto Isolated control outputs.

The CoStar is as small as a 1.25" eyepiece and weighs much less!

It also makes an effective planetary imager.

The costar is an excellent choice as a low budget autoguider and at the very low retail price of 275 it means that customers now have the option to buy a budget priced but highly effective autoguider from one of the biggest and best manufacturers in amateur CCD Imaging.

The Costar is bundles with a version of PHD Guiding from Stark Laboratories and includes USB and RJ guide cables.
