TS 3" V-Power Crayford focuser for self-adaption
This modern V-Power is one of the best Crayford focusers in our range. Originally developed for Newtonian telescopes, we are now making this focuser available for flexible adaptation to various telescopes. In our opinion, that's about all you can do with a Crayford excerpt:
♦ Steel ball bearings are oversized.
♦ A V2A steel plate is incorporated as a counterpart to the ball bearings. Even under maximum load, the adjustment is jerk-free.
♦ The maximum load capacity of the focuser is 6 kg with full precision and sensitivity.
♦ The 1:10 reduction is made of professional quality V2A steel.
♦ The focuser offers ring attachment for 2" and 1.25" accessories, as well as an internal M82x1 thread for screw adaptations.
♦ Air chamber accepts 3" fittings along its entire length, no bottlenecks in the way.
♦ The inner tube is provided with an anti-reflective thread
Motorized focus: a must for many astrophotographers
The USB_FOCUS_SET and USB_FOCUS_SET-H can be easily adapted to the UNCN3 focuser with the BR-UNCN3. The USB_FOCUS enables motorized focus and even full remote control.
Flexible connection to your telescope
The focuser is ideal for home builders and hobbyists, but is also suitable for upgrading existing telescopes. We also offer prefabricated bases for existing tubes and for DIY. The bases are linked in the accessories section. With the base, the focuser is built as follows:
♦ 85mm to internal thread M82x1 at the innermost extension position
♦ 103mm to 2" socket at innermost extension position
The draw tube does not protrude inside the tube.
