Product Details

Description:

  • New model with gear drive for heavier lifting capacity (model FOC2GLP)
  • Premium 2" Dual Speed Low Profile R&P Focuser for SCT telescopes. 
  • Will fit SCT or other telescopes that have a standard 2" SCT male thread (2" x 24 TPI)
  • Made by Long Perng (same product as Orion focuser), a leading manufacturer of premium telescopes and accessories
  • 11:1 fine focus control for backlash free and image-shift free focusing
  • Includes integral 2" extension tube for additional back-focus travel if required
  • Features drawtube tension adjustment and focus lock screws
  • Includes 1.25" eyepiece adapter

Specifications:

All measurements below are measured from the bottom end of the flat base plate. There will be an additional gap of 1-2mm between this base plate and the telescope tube which will depend on the diameter of your telescope tube.

For use with 2 eyepieces and accessories (without 1.25 adapter):

  • Focuser travel range = 0.88" (22.4mm)
  • Minimum focuser height = 2.28" (58mm)
  • Maximum focuser height = 3.17" (80.4mm)

For use with 1.25 eyepieces and accessories (with 1.25 adapter):

  • Focuser travel range = 0.88" (22.4mm)
  • Minimum focuser height = 2.36" (60mm)
  • Maximum focuser height = 3.24" (82.4mm)
  • 1.25" low profile adapter only adds 2mm to the above 2" measurements
  • Focuser includes a 1.25 collet that can be used for added extension. This can add up to 0.85" (21.7mm) to all the above 2 heights. However, it can skew the optical axis significantly and is not recommended for use with heavy 1.25" eyepieces or for imaging use.

 For use with any 1.25" or 2" eyepieces and accessories:

  • Drawtube travel is 0.88" (22.4mm)
  • Integral drawtube extension can be used to add 21.7mm (0.85") of additional back-focus travel
  • Mounting hole pattern is 54mm (2.125") along optical axis and 90mm (3.56") perpendicular to optical axis
  • Focuser weight (without 1.25" adapter) = 1lb-13.0oz (822gm)
