82fzpkZ1 Here is my auto run with the plate solving failure after a flip. Other targets were OK
You were targeting NGC2042, which is at declination -68°54'50".
ASIAIR has always been unreliable when trying to plate solve within 30º of the two poles (insufficient star database). When you are within 30º of the pole, ASIAIR plate solving will work sometimes, but fails just a dozen arc minutes away. Your target is within that 30º.
Your log shows this:
Notice that your mount has actually succeeded Meridian Flipping, and even the plate solve afterwards, that placed the mount initially 22 minutes worth of Hour Angle away. But after it has corrected that (with a movement of about 2º), plate solve has failed.
Try some other systems, like StellarMate/EKOS, INDIGO Sky, or N.I.N.A., all of which should have better databases for stars in the polar regions. Hopefully, for people who prefers the simplicity of ASIAIR, the ToupTek StellaVita (née AstroStation), when it is released, will also have better plate solving than ASIAIR.
If you search this forum, you can find where a kind poster has given instructions on how to add more star database from astrometry.net, which should help with the base ASIAIR deficiency. Some knowledge of Linux is involved.
By the way, that 22 minutes of Hour Angle error after the Meridian flip is probably caused by the mount leveling being off by 5º in the east-west direction. That is not the root cause of the plate solve failure, though.
