Baader 2" Clicklock Clamp M54a for Celestron/Sky-Watcher/Orion Newtonians (Has External M54x1 Thread) - 2956254

No more set screws.

When I first tried in my hand it locked up in the closed position and wouldn't release – it took a bit of work to get it open but once I installed on the focuser it has been great. Nicely built and it would get 5 stars except for not working out of the box.

Brilliant piece of gear

Purchased this in the hope that I could replace the original clamp on my SW 72ED, and it fit perfectly and works brilliantly. But unfortunately, it extends the optical path a little too much to allow eyepieces to come into focus paired with a 2” diagonal. But I’m going to figure a way to get that working because this is how the optical train should be attached to the telescope, period. Elegant and effective!
