Sync scope with ASCOM.SoftwareBisque fails

Sequence Generator

I am trying to “Center On” when the target starts with my new MEII. SGP uses the ASCOM Telescope Driver for TheSkyX. The plate solve works perfectly, but the the mount won’t sync.
If I just use the “Slew To”, it works perfectly for the entire night. Slews to target, tracks, does perfect meridian flips, but somehow won’t do the small slew adjustment for the “Center On”.

Gives the following lines in the log:

I know this one!

In the sequence control panel or the equipment profile, set the sync method to target offset. It has defaulted to ‘sync’ that is no longer supported by the TSX API.

Thanks Buzz. Worked perfectly. After 1 cycle it went from 290 pixels to 5 pixels on my first test, M101.

Cool! The latest beta for SGP also fixes the defaulting sync method too. Happy days.
