Prima Luce 2" Hybrid-Drive focuser for refractors
Wonderful Hybrid-Drive 2" (50,8mm with 31,8mm adapter). The mechanical precision with which it is built eliminates the problem typical of normal Crayford focusers that, during the long exposures required by astrophotography, can have camera slippage moving the sensor out of focus. For this reason there is a new Hybrid-Drive 2" focuser that adds, under the focuser tube, a rack and pinion thereby maintaining in position even heavy cameras (capacity of up 8 Kg). Below the focuser there's also a locking screw: closing it, you will be sure that your camera will not move any more!
The Hybrid-Drive 2" focuser presents the connection for 50.8mm and 31.8mm accessories (comes with a handy 50,8mm and 31.8mm reducers). It also features a convenient 1:11 fine focus gear, particularly useful when you need to focus at high magnification.
The focuser has a very long ride (95mm) to allow the use of both photographic instruments (cameras with accessories) and visual (eye and diagonal).
