Bill CCDAP can track for a preset time (which is non-linearly related to angle) past the meridian, just as ACP can. I'm not sure if CCD Commander can do this. Now, tracking SAFELY past the meridian

Thank you. You should see the results before I received my AP900! That AP900 guides through all of my misunderstandings. ncid=aolaut00050000000017 ) > > > >

Bill, ACP will continue an exposure for a given *time* past the meridian before flipping, rotating, etc. Maybe this is still not the desired behavior, but there is no delay waiting for the flip.

Richard, This wasn't the exactly the answer that the OP wanted. The fine detail is in the following: "flip at a given angle past the meridian" ACP will not do this and it's doubtful that CCD

Not to derail this informative discussion, but I would like to relate this to PHD guiding, which has a minimum movement setting in pixels (rather than seconds) and no max movement setting. My

Yes. I use CCDAP and it works perfectly for meridian flips. I believe ACP and CCD Commander also do this. Richard

Roland, What about shorter focal lengths? Should the .01 and .1 min/max numbers be a direct ratio of the focal length 3000mm and any shorter focal length. For example for 1050mm should these numbers

With a 1200GTO...is there a combination of software and rotator that can do a flip at a given angle past the meridian...and reaquire the same guidestar and resume exposure?

Very nice and thanks for the nums. I have about the same setup with a C9.25 and the ST2K, so I will go your min/max a try. Ken min, and numbers else on this transparency. round. This x 4 min as

With the eFinder and Sbig remote guide head, I used 0.05 for the min, and 1.50 for the max. The eFinder is only a 100mm f/l 'scope' so these numbers are very small. Guide rate is 1x and I have not
