Here's some of what I posted on 10 u forum:
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.
I also have wait for meridian checked. Most important of all is to display the LST on the hc and make sure that it is not locking up at 12 00 00. This would usually happen when I would do daytime testing. I would shoot one image b4 the meridian crossing and the flip would work but at night, after one or two images b4 the meridian, LST would lock up. Firmware 2.14.4 solved this problem........................Gunny
