TS UNCR2 2″ Crayford Focuser for Refractors and RC Telescopes

The TS UNCR2 is a short focuser with only 60 mm height. The excellent workmanship make this focuser to one of the best in its class. Through the short length, the focuser can be adapted to almost all refractors with tubes from 80 mm diameter. Ideal if the otherwise good refractor is to be retrofitted by an excellent focuser for astrophotography or heavy accessories.

The adaptation of the UNCR2 to your telescope:

At the telescope side, the focuser has a connection matching to a dovetail ring with 72 mm outer diameter. We will be glad to offer you a custom adaption to your telescope.
For Skywatcher refractor telescopes and on the important M90x1 connection thread we offer ready made adapters. You can acquire an individual adaptation to your telescope from us with the article Sonder105.

The advantages and features of the TS UNCR2 focuser:

♦ Besides the 2″ and 1,25″ compression rings, the focuser offers a male M65x1 thread for threaded adaptions. That is important mainly for astrophotography.
♦ The focuser is only 60 mm heigh, so not much valuable optical way gets lost, you will have no problems with the focus position.
♦ The focuser has generous 72 mm travel.
♦ Reinforced ball bearings and V2A bearing surface offer maximum rigdity and full functionality even after many years where aluminum slowly abrades.
♦ The 1:10 speed reduction has professional quality and is also made of V2A and hardened steel.
♦ Massive steel rails are worked into the drawtube as counter surfaces for the ball bearings to ensure a smooth motion.
♦ The drag is adjusted with a friction screw. Locking the focuser becomes unnecessary, as the focuser keeps the position, even at high load. However, a knurled locking screw is built in.
♦ Steel parts and gear drives are designed for long-term operation under heavy load, especailly for astrophotography. The stainless steel ball bearings are combined with bearing surfaces also made of from stainless steel, so nothing can incise into soft aluminium.
♦ The drawtube is furnished with anti-reflex baffles to improve contrast. However, you can sink 2″ accessories into the focuser.
♦ A cogwheel takes the movement of the optional TSACUMOTORFOK motorfocus. However, a friction clutch allows manual operation. The power is transmitted by a speed-reducing drive, so exact focusing is guaranteed also with motor drive.
