Starlight Instruments Adapter 2.0 for Celestron SCT Telescopes

This adapter is specifically designed for Celestron C11 and C14 Schmidt-Cassegrain telescopes. It threads directly onto the visual back of these specific models.

While this adapter is precision-engineered and optimized for the Starlight Instruments FTF2015BCR focuser, it is primarily intended for that specific pairing. We recommend using it with the FTF2015BCR to ensure the mechanical alignment and stability required for high-end observation or imaging.

Yes, this adapter threads directly onto the rear cell of your Celestron SCT, effectively replacing or bypassing the standard visual back to provide a more secure, threaded connection for your focuser.

The primary benefit is stability. By threading directly onto the telescope's rear cell, this adapter eliminates the flexure and potential slippage often associated with standard compression-ring or set-screw connections, which is critical for maintaining precise alignment during long-exposure astrophotography.
