I tested the MF indoors today and it is clearly a limits setup issue. The last version of the ASCOM driver (0.94N) works fine with Voyager as long as the limits setup in SiTechExe allows Voyager to manage the MF.
Here´s the relevant setup screen in SiTechExe:
I have set the Meridian Limit West (Degs) to 0/-180 and the Meridian Limit East (Degs) to 0/180. So the limits after which the mount should stop tracking are precisely at the meridian. Some people leave some extra margin, but I think that this is not really important, since the key parameter is the Track Past Meridian Overlap (Degrees) . This is the region past the meridian limit where you allow the mount to keep on tracking. More importantly, it is the region where a GoTo will actually produce a MF.
So I set the Track Past Meridian Overlap to a little bit more of my maximum exposure in Voyager. If this value is set to zero then the mount stops tracking at the meridian limit.
Finally I left the GEM Auto Flip GoTo checked.
In such a way the mount will continue tracking the value of Track Past Meridian Overlap degrees past the Meridian Limits (which in my case are set precisely at the meridian) and while in this overlap region it will flip whenever Voyager issues the MF GoTo.
In Voyager all the time setting in the Mount Setup panel and the Session Meridian Flip tab must be within the Track Past Meridian Overlap region.
So ready to do my first full session with this new mount.
Thanks a lot for your help,
Note: I deleted my previous post since I found out I made a mistake in the Meridian Limits Under the Pole which could result in a pier crash. The signs were inverted.
