The best thing to do here is to find a used Complete ETX90 EC Base
W/Controller and trunions (tube mountings), and just transfer the tube
to the new base. I would advise getting the Autostar 497 controller, it
has a larger database, and is easier to update.

I had both the RA and EC bases. The RH  trunion had to be heavily
modified to fit the AT fork arm. This included making my own clutch
assembly. It works great, and has no slippage, and the GOTO is dead on.
I would not go this route unless you have experience in this area. I did
see online at: http://www.scopelogic.com/Item.aspx?id=0101 that they
have a RH tube adapter made of machined aluminum for around $75. Looks
like a really nicely constructed piece. I may buy one myself just in
case. But for right now, I'm satisfied.

Good Luck,
Bill

Can you tell me if any of your readers has modified this scope and ended
up with a reliable "go-to" system?
