All, Want to give a big shout out to the AO device. The day I got the AO8 for my ST10 I cut the guiding cable to the mount and never looked back. What a relief to not worry about gear backlash, guiding calibration etc ever again. I wish AO development would come up with a skinnier version. Moving the glass on a hexapod style mount eats less space than current tilt actuator! Keep up the great product! Cheers, Gert PS wonder what happened to the very few other manufacturer that tried to do AOs. But that's not SBIG's problem.
