My 12inch LX200 and the 130/780mm F/6 TMB Refractor with the LXD750 Goto mount. I use the 12 inch for observing only, and
I use the refractor for CCD imaging and astrophotography. I have only had the mount  guide ready
for a short time. Had to make an adjustment in the Dec axis after this secssion, and train the PEC. I  have not made any astrophoto's at this time.
