Starlight Instruments FTF2020BCR-LW - the ultra-lightweight 2 Inch Focuser
The proven 2020BCR has been further developed to achieve the best possible weight savings while maintaining maximum stability. The focuser´s housing has been notched out and the draw tube has been custom machined, now the focuser weighs only 0.894 lbs. (0.405 kg).

At the same time, it remains as stable as the normal drawer and can be loaded up to approx. 4 kg.

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 35.7 mm. So the focuser can be used with telescopes with short focus position.
Telescopes with side view (Newtonian) - suitable bases and spacers are linked. However, it is not recommended to use this focuser for Newtonians, as the drawtube will protrude far into the inside of the tube when the shortest focuser position is set. For Newtonian telescopes, we recommend the FTF2015BCR (or FTF2015BCR-LW) instead, whose smaller adjustment range allows for a shorter drawtube.
