Codice articolo: FTF2020BCR

Starlight Instruments Feather Touch FTF2020BCR 2"

The 2" high-end focuser offers 50 mm of focusing travel and is suitable for DIY and telescope upgrade.
♦ 2" receptacle with compression ring at the eyepiece side.

♦ Dovetail on telescope side with 69.6 mm diameter - matching telescope adapters are available

♦ Adjustment range of the drawtube - 50.8 mm (2.0")

♦ Minimum height at inward focuser position only 37 mm - but the drawtube then protrudes much at the telescope side, therefore the focuser is not well suited for Newtonian telescopes.

♦ Guaranteed no tilting when locking the focuser position

♦ 10:1 dual speed for precise focusing

♦ Especially precise 2" clamping - important for astrophotography

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 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.
