* For all RCF focusers you must specify whether you want a flat or curved base. For curved bases, you need to specify the radius. If you don't, you will get the standard size radius. Please specify your selection by one of the two methods listed here:


Select one of the options below to add your desired specs to the shopping cart.


Place a note in the shopping cart Comments area specifying "Flat Base" or "Curved Base" and the appropriate radius for the curved base. (Diameter = 2 x Radius)


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.

The Kit versions of the RCF are shipped unassembled. Proper assembly is the responsibility of the customer. JMI will not be responsible for any damage during assembly. Kit versions can only be purchased directly from JMI.
