If you ever take the secondary mirror off your Schmidt-Cassegrain to photograph with a camera in the primary focal point, you’ll have to re-collimate it afterwards. With these collimation screws for a SCT with Fastar from Bob’s Knobs, you do it with your fingers instead of with a screwdriver.
With a Fastar telescope, the holder of the secondary mirror is constructed differently than with an ordinary SCT. This set is intended for the 9.25-inch model with Fastar. Check beforehand whether your telescope is truly Fastar-compatible. Cameras for this type of photography can be found among the astro cameras in our range.
Replace the screws one by one and then collimate on a defocused star. If you often take the telescope with you, then a Upholstered backpack for the C9.25 Convenient for on the go.
If your 9.25 inch doesn't have a Fastar, check the Set for the regular 9.25 inch SCT.
