The Baader 2" RT2 Diamond Steeltrack Crayford Focuser for refractors can be used with this adapter set to enable it to be attached to several different brands and sizes of telescopes. The RT Steeltrack Adapterset consists of 3 parts:
- Part 1: Expanding ring. Has M68x1.0 internal thread on one side for attachment to the focuser, and M80x1.5 external thread on the other side. Fits directly onto Zeiss.
- Part 2: Large lock-ring. One side slides over part 1. The other side has an M90x1.0 internal thread. 3 chrome grip 'spokes' permit easy 360-deg rotation and locking of the focuser.
- Part 3: Base ring. One side has an M90x1.0 external thread to connect to Part 2 above. The other side has a slip-fit 96mm OD flange. This slips inside of tubes with an ID of 96mm or slightly larger. ID of this side is 82.9mm.
You can attach this via the M90 female thread to GSO-made 6" and 8" RC telescopes. The 96mm flange plate will fit many refractors sold under the Celestron and Sky-Watcher brand names.
