Declination cable issue - 22" U.C.


 

? After many years of owning Obsession telescope & ServoCATs, it wasn't too late to make dumb mistakes. The Alt cable on my 22" UC came out of the groove when I was moving the telescope minus the truss tubes & UTA a few feet to a more level ground (I neglected to secure the mirror assembly to the ground board before moving it with the wheelbarrow handles).
? I got the cable back in the daytime, but last night, despite 5 alignments, objects were still way off (not in the eyepiece), even though the AN did not read 0.00. The AN read 0.5-0.7 and 0.5 when it finished the GoTo.? It tracked fine after I slewed to the object. From what I read on a recent thread, the Alt cable going into the groove needs to be closest to the mirror, at least for the Obsession Classic. On mine the cable into the groove is furthest from the mirror. I assume that was the cause of my problem??? Any other possible causes??
?? I should have listened to my non-astronomy wife when we were testing the movement in the daytime and she said it seemed to move side to side. I do have 2 Teflon pads on both sides of the ground board to keep the mirror assembly from moving, especially when traveling in the car.?
?? Any advice would be much appreciated.
Thanks,
Al



 

WHAT? It fell off because the furniture glides pulled out??

Gary is the man. The dentist is not.


 

Apologies for the late replies - we took a rare few days off to visit family in the NE. Just back in - give me tomorrow morning to answer. If you've emailed me direct (I had been checking direct emails) then I'll respond that way.

I'm not sure what you mean about groove furthest from the mirror?

UC-22 and the servocat... don't get me started... :)?
Gary is the MAN. The dentist? Not so much!
