Quote:The pics in the review show the mount on a wooden deck. I would not think that a wooden deck would be that stable.
Quote:Another thing I would like to share is about the "to park position." John mentioned â€œI pushed â€œto park position,â€ and waited for the motors to engage as the manual said they would. Nothing happened. So, I manually aligned the scope in a vertical position, using a level to ensure precision, pushed "to park position" again, and shut the power off.â€ Actually I would not expect the motor move if the first thing was â€œto park positionâ€ when power on. The initial (default) position when power on is park position no matter whether it actually is. If after slew and then to park position, I bet the motor would move.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote: I also have a MT but haven't yet tried to use it for AP. With respect to field rotation, doesn't it matter where you are pointing in the sky ? I mean if your target is closer to the NCP, wouldn't you be able to shoot for somewhat longer than 56 seconds ?
