I think I may know what's going on here, but want to ask anyway.
I have a 9.25 SCT mounted with a Stellarvue 50mm finder (14 oz)... and a telrad.
Both are offset to my left at back of OTA.
On one side of the mount, the OTA is nose heavy; on the other side (180 degrees) it is tail heavy.
No balance issue in RA.
The mount tracks ok, but I wonder if this is placing unnecessary strain on the dec motor as it slews?
My best guess is the imbalance of the offset finder & Telrad.
Wonder if anyone else has experienced this and what the remedy might be? Equal weight opposed to the right side of OTA?
