2” diagonal for SCT

I am a beginner and I have not used the best, most expensive of anything yet. However, this diagonal has a beautiful finish and eyepieces slide in and out smoothly. It threads on easily and holds tight.

Best diagonal for SCTs

Because it treads on to the OTA, this is the best diagonal for a SCT. It is secure, and won't fall off if you use it as a handle. Eyepieces lock tight. Optically it is excellent.
