I've used Baader ClickLock's for years. They are excellent. I bought this 1.25" / T-2 version to replace a Baader focusing eyepiece holder, which worked very well but had lots of little screws (4 actually). Normally, I would give the ClickLock a 5* rating but this version also has a fine focusing ring on the top. Personally, I have found it unusable in practice though, as usual with Baader, it's very well engineered. You have to slightly loosen the ClickLock adjust the fine focus and then retighten. I could see that spelling disaster with gloved hands.

The Badder clicklock is a great piece of kit, wish I had it a long time ago. Thanks, Geoff.

High quality item. High quality delivery.

Bought to go with the Baader Flipmirror, my existing eyepieces can now be used, all fits together well, strong construction.

Purchased to go with the T2 prism which is great. So satisfying not having to fuss around with thumb screws when changing eyepieces. The Baader diagonal set-up is worth the price for that convenience alone, never mind the great optics.

its expensive but allows solid attachment of Ep to my quark via the thread adapter.

Another top quality piece from Baader. Another happy buyer from FLO.

Wish I'd bought one of these years ago.

A joy to use (no fiddling about with 2 small screws with cold hands on a dark night).

Has the benefit of not marking your eyepiece (unlike the 2 scew holder).
