FTF2015 Focus Adapter for Celestron SCT with Small Thread | Feather Touch from Starlight

You normally focus a Celestron SCT by moving the main mirror, but for photography or planetary imaging you want to be able to do it more precisely. With this FTF2015 adapter for Celestron with the small threaded connection, you can attach a Feather Touch FTF2015 from Starlight Instruments to your telescope. The mirror is fine-tuned, the focus mechanism does the rest.

The small screw thread is found on the 8 inch Celestron, among other things. the C8 on a CGEM II mounting. Celestron also uses a large size, so measure the connection of your telescope before ordering.

Also, check if your focus lens is really an FTF2015. A tip for focusing yourself: work with a Bahtinov or other focus mask, Then you immediately see if you are at the sharp point.

If your Celestron has the large screw thread, like the C11 and C14, then choose that. the FTF2015 adapter for the large wire.
