So you did move the focuser ? Back to its first auto focus position ? I’m sorry if it seems like I/we are going over the same thing but it’s this detail that, at least I think, could be the source of the issue. Is it possible that you made a mistake in recording the original focuser position ? Another thought that crossed my mind ( that also requires moving the focuser ) is your scope uses a rack and pinion focuser. Is there any backlash what so ever in the rack ? And I mean ANY ? It would take so little to not to reliably return back to the exact position despite what your AIR is reporting on the EAF. To prove this you could move it and move it back to where you think you had it and see if the flat changes again ?
