Frustration with U-C 108 tilt adapter system reliability issues - Forums

Hi U-C 108 users!

I have reached the end of my patience with the U-C 108 Tilt adapter system. I was in the original 100 purchasers of this scope and it has been a fight ever since, but this last round has burned me enough!

Every trip to a dark site, I have to be worried about the Tilt. I installed a Wanderer ETA just to try and maintain a flat image. I am using a ZWO ASI6200M on the scope and after a dark sky trip this last weekend, set up the scope in the back yard so I could do some city based imaging. Tuesday night. I went from near-darkness here in Vancouver, Canada, (about 10:15pm to 3am fighting the knobs.

The tilt was so bad, Aberration Inspector could not finish a run. I am pretty certain, having to make adjustments literally every outing does not bode well for longevity of the apparatus.

My 108 is first generation and I have asked William Optics to fix the scope. I am not sure if they will put in the new “reversed kit” or tell me to find another solution but II have no hesitancy putting on the adapter you had made by Telescop Express.

Can you, (or anyone who has purchased the adapter from Teleskop), let me know what the product number might be or description so I can order one?

Thanks in advance.
