Hello folks,
Last night I was trying to image M 106. Whenever i tried to start my imaging sequence, for some reason SGP determined that my scope needed a meridian flip, when I knew it did not. The object was still way far east of the meridian. Eventually, the meridian flip would fail and the sequence would abort. Why would this happen?
I am running my imaging train on top of a Paramount Myt and use the Skyx ASCOM driver to talk to the mount through SkyX.
The debug logs of the meridian flip attempt are as follows -

This line from above log seems fishy -> [03/14/18 02:11:54.626][DEBUG] [Sequence Thread] Meridian Flip needed, Hour Angle >= Degrees Past To Flip: 137.324835377593 >= 0.5
I am also attaching screenshots of my ascom driver settings and SGP telescope/meridian flip settings.
Would appreciate any help. Thank you!
