The brand new William Optics RedCat telescope is an alternative to the widefield lens shooting with 250mm of focal length. With the helical focuser, focusing can be quite time consuming process even with the Bahtinov mask (especially with narrowband filters). Our autofocuser will save you time and frustration by providing pinpoint stars on your beautiful photos of the cosmos.

Listening to your feedback and following the new developments from William Optics, we have refreshed our line of cat series autofocusers.

With the extension block (3D printed or aluminium), we raised the telescope just high enough to snugly fit the motor between the telescope and the dovetail. This results in a balanced, compact solution, leaving ring available to other accessories, like William Optics guide scope plate that comes with the SpaceCat. Our kit is compatible with 110 and 210 dovetails that come with the cat telescopes.
