The Baader M90 x 1 adapter for Steeltrack RT allows you to attach the Baader Diamond Steeltrack Refractor focuser to GSO Ritchey Chretien telescopes which have an M90 x 1 thread on the rear flange (such as the 6″ and 8″ models). On the focuser side is a series of Delrin-tipped screws to securely hold the focuser in place around its S88 dovetail.

For use with GSO RC telescopes, it may be necessary to use one of the extension tubes that came with the scope, otherwise the focuser drawtube may not travel all the way in.
