When it comes down to critical component selection for your reflector telescope, a Crayford focuser is a sure bet. This 2" focuser from Jim's Moble Inc. (JMI) is solidly constructed and uses a unique design which pulls the traverse tube to the bearings utilizing a flat stainless steel bar rather than pushing the tube against them with the pinion rod . The look and feel of this precision instrument reflects the passion of the machinist that created it. This picture does it no justice. Truly Superb!
