Then DO NOT buy from Obsession. Because the dentist ignores complaints or tries to pass them off to subcontractors. Yeah It's been 5 years or more. And never once has he admitted he, or whoever built my UC-22, screwed it up.?
No worries, I fixed his screw ups. Just sad that he never ever owned up to it.?

It's like you buy a BMW, the A/C fails in the first month, and BMW says "Sorry, contact the compressor manufacturer for help!"?

I bought my UC 22 with Servocat Drive and Argo Navis in 2015. I have used it extensively. I can identify with your some of your inputs/problems and empathize with your experience. I did make a number of modifications (Markless cable stop altitude drive, oblong mirror cell guides [keep mirror from moving side to side], additional VMB guides [limit movement from torque of altitude drive], removed powered ground board connection, installed lithium battery connection in rocker box, and modified rocker box to ground board pads to improve performance. This was definitely more modification involvement than previous truss Newtonians I have owned. But, every truss Newtonian I¡¯ve owned required tweeking and/or some minor modifications. I guess for the relative portability and price I paid compared to other 22¡± options at the time I accepted the ATM work required. I can understand where others might not.
I always transport/move it using wheel barrow handles and ramps with the altitude cable and altitude encoder bracket always attached (I do not attempt to lift the mirror and VMB into place). I never have a problem with the altitude cable coming off during transport or in use. I have used the telescope with both the Argo Navis and Nexus coupled with the Servocat. The telescope tracks well (no problem doing EAA with a Mallincam) and all speeds/movements of the hand control work well. For my telescope, accurate GoTo performance with the telescope requires using MPoint(Nexus) or TPAS(Argo) correction. Both MPoint and TPAS work well with objects over most of the sky well within the FOV of a 17mm Ethos eyepiece. I have now reverted back to using the Argo Navis because it allows storing persistent mount errors and synching after the model is in place (At this time, Nexus MPoint does not allow this). I saved ECES and Collimation error data which is persistent). So, after the initial 2 star alignment, I only do a 4 star TPAS calculation(IE) taking 10-15 minutes for accurate GoTo performance across the sky. The collimation holds well from the zenith to low altitudes.
I admit the UC 22 is not the best telescope out there and that DK could improve the design and probably provide better support ¡ But, overall, I feel mine is a very good telescope ¡ the optics are very good and the telescope performs consistently well. Over my 7 years of ownership, I have observed thousands of objects with it and continue to use it without problem. My impression/experience with the UC 22 is different than yours. Of course, I respect your opinion and so do others. But, for me, seeing your inputs over a number of years on every related forum (and your communication with fellow astronomers we have encountered in common) that the Obsession UC 22 is the worst telescope ever and no one should ever buy/own one is very disappointing. I have no immediate intention of doing so, but, I feel you may have made it almost impossible for me to ever sell my UC 22.
Just my input/feelings ¡ Jim
