Product Description
The Feather Touch provides very precise control for both critical CCD imaging focusing and high magnification visual observing. Unlike some heavy add-on rear cell Crayford focusers, its light 5 ounce weight doesn't require a counterweight to keep your tail-heavy scope balanced. The focuser is precision-machined and anodized black with a brass fine-focus knob.
The focuser has two concentric focus knobs. The larger black ribbed outer knob provides standard speed focusing, while the ribbed inner brass knob provides 1/10th-speed fine focusing, making the Feather Touch MicroFocuser extremely accurate. A built-in stop prevents the primary mirror from detaching from the focuser.
The Feather Touch CPC-800 MicroFocuser is easily installed in place of the original focus knob on the Celestron CPC-800/RASA 8", NexStar 6SE, C8Edge HD 8SE SCT and SkyWatcher 150/180mm Maksutovs telescopes only. It is not compatible with other Celestron or Meade 8" SCTs.
If your telescope is less than a few years old, check the style of the back cell to see of this is the focuser you need. If your telescope rear cell has a flat back, you need the standard C8 MicroFocuser. If your telescope has a raised triangular pattern on the back, this is the correct version of the focuser for your scope.

Just one word of warning/heads up: on the 6SE (which does not have much space between the focuser and the rear SCT thread) you may find the clearance is not enough for certain imaging train accessories. For example, I found I was not able to attach my Celestron off-axis guider directly to the rear cell (i.e. at prime/native focal length). Thankfully, I use a focal reducer/corrector most of the time anyway, which pushes the OAG back *just* far enough to clear the focuser. (Posted on 10/13/2018)
