    I have the AO-8T. With a 819mm FL telescope I had no problem keeping the guide star on the mirror for long periods of time before bumping occurred. I now have a 3000mm FL telescope and even with very good polar alignment it seems it starts having to bump the mount after 25 min. or so. I realize there's a different image scale involved but was wondering with the AO-X how much more time would that buy me due to the larger mirror size.is it about 30% larger?...thanks

    The larger window of the AO-X is for larger sensors, not larger telescopes. The AO-X is also faster than the AO-8T, since it uses electromagnets instead of motors.

    The tilt range of the AO-8T is actually larger. So switching models will make bumping more frequent, not less.
