The FeatherTouch SCT MicroFocuser by Starlight Instruments
provides the smoothest control for fine focusing Celestron CPC800 telescopes.
Two focus knobs allows for standard or 1/10th-speed focusing, making the FeatherTouch MicroFocuser extremely accurate. Excellent for both imaging or visual observing, this focuser is precision-machined and anodized black with a brass fine-focus knob.
The SCT FeatherTouch MicroFocuser is easily installed in place of the original focus knob on the Celestron CPC800, the Celestron NexStar 6SE, the NexStar 8SE telescope, and the RASA 8-Inch. A built-in stop prevents the primary mirror from detaching from the focuser.
This model is not compatible with other 8-inch SCTs.
OPT Product Number: SI-FTM-CPC8
If your telescope is less than a few years old, check the style of the back cell to see which version of the Feather Touch® SCT Micro Focuser you need: If your telescope has a flat back (left picture), you need the standard “C” Micro Focuser. If your telescope has a triangular pattern on the back (right picture), you will need the “CPC” version of the Micro Focuser.
NOTE: For the Celestron 6SE, you will need to measure the outside diameter of the flange of the stock focuser (the part of the stock focuser that mates to the rear cell, as Celestron uses 2 different size of flanges, 1 that is 1.5″/38mm and 1 that is 1.6″/40.6mm.
