Feather Touch® 3.5" Diameter Dual Speed Telescope Focuser Kit, 4.5" DTT, and Brake.
The photo of the 2 telescopes with Feather Touch focusers is courtesy of Bill McLaughlin.
The telescope must have at least 4.35" of clearance for the draw tube to go inside of the telescope, if not the draw tube will "bottom-out" and give you more back focus.
Please select the proper tube adapter ring and end cap that are needed. If you need a Finder Scope Bracket, in the drop down box please pick the one that you want. If you do not need one, please pick the not interested box.
Make your selections from the drop down boxes that are to the right of the image of the focuser.
