| This Starlight Instruments Feather Touch CPC-1100 MicroFocuser replaces the standard focus knob on your Celestron CPC-1100 11" Schmidt-Cassegrain telescope to provide the smoothest possible manual dual-speed fine focusing control. Although the Feather Touch Micro will not eliminate any image shift already present in your scope, it will greatly improve your ability to hit the focusing “sweet spot" without shaking the tube while you are imaging or observing at high power.
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 6 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 gold 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-1100 MicroFocuser is easily installed in place of the original focus knob on the Celestron CPC-1100 only. It is not compatible with other Celestron 11" SCTs.
If you are not sure if you have a CPC or GPS version of the 11" Celestron, you can easily tell by examining the scope. If the base of the scope is gray, it’s a CPC. If the retaining ring between the standard focusing knob and the rear of the scope is orange, it’s a CPC. In general, the 11" CPC went into production in 2005, replacing the 11" GPS version.
