Good news for now. Over on CN Jari responded with the following:
For some reason the mount doesn’t like doing the flip after the meridian has been crossed, I have seen the exact same error. The following settings work for me, so I haven’t investigated this in more detail:
SGP: Minutes Past Meridian to Flip = -10 minutes
Handset: Flip Slew Tol = 3 degrees (~12 minutes of tracking)
Handset: Flip Guide Tol = 5 degrees (~20 minute of tracking)
I don’t do exposures over 10 minutes so I don’t use the “Wait for Meridian” option, and the times have been set to reflect this. If you use that option then you should be good to go with flipping at -2 minutes and having 1&2 degrees for tolerances.
In any case these settings cause an early flip so make sure that your equipment doesn’t collide with anything.
My response was the following that I and others may want to try:
Thanks for the assistance in this matter. Turns out that Vehnae-Jari had the answer and is therefore the winner of my grand prize for solving this mystery. You win free homebrew beer the next time your in my neck of the woods.
Seriously though Jari, I can't thank you enough. Here are my present settings for the daytime run that worked three times and resulted in successful meridian flips:
SGP: set to -5 minutes in auto meridian flip
HC on 10u: flip slew tol = 3 degrees
flip guide tol = 5 degrees.
It may also be important to turn off your telescope connection in the planetarium software after you have slewed to your target. I’ll have to investigate this further, but it seems that the time base was off in this program and may have contributed to the problem…Happy Trails…Gunny
