Baader T-thread to 1.25 Helical Focuser

This is an excellent piece of kit. I bought it to improve the focusing on a standard Synta style R&P rather than go to the expense of a aftermarket Crayford. It works a treat, is lightweight & doesn't add much to the optical path. Moreover, it's very well made & has a really smooth action. It does rotate but if you're only using an eyepiece in it, then it doesn't matter.
