Thanks Ken.
I tested auto-meridian flipping when I got home from work with the current betas 2.5.2.3 and 2.14.6 (10U).
I simply connected the mount in my sequence, connected my mount to Cartes du Ciel and slewed to a point just east of the meridian and east of my flip limit. I nudged the mount west to within my limit (-5mins of meridian) and clicked Run on the telescope tab. The auto-meridian flip worked and countdown to meridian was reporting correctly.
Despite the forecast I am waiitng for the clouds to clear to test when running a sequence. I have the 10U log running as well as collecting logs from Per's ascom driver.
If I have a problem flipping I will downgrade the 10U beta firmware to 2.14.4.
