Starlight Instruments 2" Feather Touch Focuser
Focusers from this manufacturer are among the best. All bearing parts are made of hardened stainless steel for best possible smoothness even at maximum load. The focusers have no signs of wear. The adjustment is still like on the first day even after years. Hardened stainless steel running wheels and a hardened stainless steel bearing surface guarantee smooth yet very accurate adjustment.

Adapting the focuser to the telescope
The focuser has a ring dovetail that fits various adapters from Starlight and from TS-Optics. This allows you to connect the focuser to the telescope.
Telescopes with rear view (refractor, Cassegrain ...) - the housing of the focuser is very short, only 37 mm. So the focuser can be used with telescopes with short focus position.
Telescopes with side view (Newtonian) - suitable bases are linked. However, it is recommended to use an extension, otherwise the drawtube will protrude too far into the inside of the tube when the shortest focuser position is set. So when calculating the focus position, the height of the focuser (37 mm) must be added to the height of the spacer.


For Newtonian telescopes we recommend the R20-1.0. The spacer has 25.4 mm height. The effective height of the focuser is then 62.4 mm + the 6 mm height of the Newtonian base.
