Last night I went out and was getting great guiding, .24" to .5" pretty much the entire session with a focal length of 1422mm. But when M81 transited the meridian, the AM5 didn't do a flip, even though all the ASIAIR Plus (2.1, latest firmware) settings were correct. I set it to 3 minutes before the flip to stop guiding and shooting and 3 minutes after the flip to re calibrate guiding and start tracking and imaging again. I waited a few minutes and then decided to manually do the flip and go to M81 and start imaging again.
Is DST the problem? ZWO says that the mount's time should read exactly 1 hour early, and mine did. There's no settings in the mount itself to change local sidereal time or turn off DST, it appears to be all done in ASIAIR Plus. I don't see any setting in ASIAIR Plus either to turn off or on DST.
What can I do to make sure the flip is automated? Should I try lengthening the before and after flip times to 5 minutes rather than 3?
I've long thought that DST is one of the most idiotic ideas humans have ever come up with. Now that it appears to be messing with astrophotography, I dislike it even more!
