5) As measurement 4 made me suspicious of my OTA offset, I include a picture of measuring it. It looks close to 14.5 to 15 inches, or 0.38 m, to me. See picture below. However, INDI seems to work better if I use 0.5 m. Then the dome rotates far enough in the E and W positions to not occlude the scope. Unfortunately, I have not been able to find and E-W offset that will center it. It seems to want a very big number, like 1m, that makes no sense, and only works on one side of the dome.

So what am I doing wrong?

As always, my sincere thanks,

Scott
