Meridian Flip - Looking for Configurable solution

  • Posts: 148
  • Thank you received: 19
Since all of the last work on status and mount state/position ect that largely solved MF issues, I ran into an interesting case last night that I THINK can be solved by the correct choices in settings somewhere:
1) mount and EKOS operating fine gathering images
2) MF is marked and executes - guide is suspended as expected - a nice 75 second flip which is normal for my mount and slew speeds
3) the coordinates for the slew are correct (M33) and I expect  to be out by some margin

At the exact same time as per Murphey's Law, the sky goes to crap at EXACTLY the same time which results in "solved failed:

So post flip align fails but guide starts up and I wind up with a load of images of a starfield close to M33 - now notice the STATE of Align for the rest of the session - "In Progress"  :-) :
 

So the question is:  without changing code, is there a known way to have the WHOLE sequence abort and shutdown  (as in end up in PARK) after the two failures to solve - this appears to be more of a logic hole than anything as after a flip, if you can't align then you really cannot do anything else.

Thanks in advance for any tips ...Cheers
