SCT Adapters thread onto the standard Celestron C8 back to allow use of standard 2" eyepiece accessories — such as our Everbrite diagonal mirror.

Where SCT fork swing-through clearance is an issue, attach our Flat Top 2"-1¼" Adapter to your 1¼" eyepieces. Your 1¼" eyepiece now becomes a low-profile 2" eyepiece.
