Gone are the cumbersome thumbscrews. Gone are imprecise and wobbly holders. Now, with a simple twist, 2-inch eyepieces and accessories are instantly locked with such strength that they can literally support an entire telescope without slippage. Simply grasp the rubber-knurled outer collar and lightly twist - that's all there is to it.

What's more a knurled clamp lever is also provided for added convenience and to give a quick visual indication of clamp position and each Clicklock is provided with the necessary wrench to enable adjusting the rotation of the clamp for positioning the lever in the most convenient location.

Just what I needed

Was using the standard Celestron 2" adapter on my C8 XLT and it didn't quite lock down my imaging train as securely as I would like while using the starizona .63 reducer/flattener. This clicklock adapter feels like it has full contact with the barrel and no play at all. Does not take much to tighten down. Overall great adapter.

Thread 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.

My 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.

Excellent 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!
