JMI - RCF-1 (Reverse Crayford Focuser 2 ") with Motor

Details

Factory Assembled with Motor

Please Note: When using a laser collimator, keep in mind that there will be slight deviations in the laser beam when moving the drawtube through the full length of travel. This deviation is not noticeable visually, is only a small fraction of the amount present with a normal rack-and-pinion focuser and is completely eliminated with the higher quality of most of the NGF focusers.

Due to the design of this focuser, the knobs are at a 90-degree orientation from most, placing the drive shaft perpendicular to the optical tube when using a curved base.

Product Series

The Reverse Crayford Focuser (RCF) is a light-weight, low-profile focuser with a new revolutionary design - JMI′s low-cost, high-quality answer to plastic focusers. The reverse Crayford design gives zero image shift and zero backlash. (U.S. Patent No. 6,297,917)
