Thanks John. I talked to Claude at Astronomy and Electronics (where I got my setup) and he is getting one from Takahashi. Sounds like the same thing at a higher price. In addition, since you have been down this road, am I correct in assuming that the computer USB / Serial connection to drive the mount in 'goto' mode is using the supplied serial cable x 6 pin round plug cable? So that would get me the 'goto' capability while the autoguider cable from the SBIG to the autoguider port will give me the guide adjustment signals?
I had this all working fine with my old HEQ-5Pro. I just got the new scope and mount set up last night. Tonight is figuring out the electrical side, with next to no manual. Gotta love Takahashi for that..
