Description

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 a Finder Scope Bracket is required, please select appropriate option from the drop down box.
