United StatesThread Pitch Incompatibility with my CPC 9.25-inch SC
I was very eager to install and use the Baader 2” ClickLock Adapter (BA-CKSC-2) on my second-hand Celestron CPC 9.25-inch XLT SC optical assembly. Unfortunately, the thread pitch on the rear cell of my particular SC prevented this. This adapter comes with the newer 2” - 24 tpi and binds on my telescope. The Baader 2” ClickLock is a beautifully-made, precision adapter. Thus, I had to reluctantly return the ClickLock to OPT for a refund. If Baader made the same 2” ClickLock Adapter with my SC’s rear cell thread pitch, 1mm as best I can determine, I’d buy today. Still looking however.

United StatesMy first OPT buying experience
I recently purchased a number of items from OPT. Included were a Baader Clicklock : 2” dielectric diagonal, 2” adapter for smaller SCT threads, and 2” to 1.25” reducer. All the items were delivered in perfect condition. I haven’t had a chance to use them all but I am confident they will perform as advertised. More importantly, the buying experience was wonderful. OPT had all the items I wanted in stock, and everything was delivered in two days. I look forward to ordering more things from them in the future. The SCT adapter threaded perfectly on my 150 Mak and adjusting the position of the clicklock lever was a breeze. This device is a perfect replacement for my old thumb-screw visual back, easy to use and the grip on my diagonal is rock solid. And changing the position of the diagonal is quick and easy. I wouldn’t use anything else.
United StatesExcellent SCT Solution!
I was looking for a way to attach a 2” diagonal on my 12” LX 850 ACF without ******** one on every time I wanted to go visual. This is perfect! Well engineered, and incredible holding power. One caution, the tolerances are tight on the baader SCT threads. If it is a really tight fit, I would recommend a light sanding on the inner diameter of the adapter 2” SCT threads, clean off the dust and apply a light lubricant or anti-cease compound to the threads. Then the adapter will screw on with absolutely no play in the joint. Highly recommended!
Baader ClickLock
The Baader 2" ClickLock is a great visual back for my Maksutov-Cassegrain, it hold my 2" diagonal in tight without marring the barrel. I'm very happy with it!
