Stuart,

That may be the issue. I usually start imaging in the east, but I had a few hours before the target was high enough to see so I started collecting frames on another target west of the meridian first. I will have to try it the next clear night.

Dave, I believe you must always initialize on a star East of the meridian. Could that be it?

Hi Stuart,

I made that mistake early on when I first got the mount. I now make sure that the time displayed in the APCC status window it correct when I start up.

I think I am just not understanding the process for starting up and the initial sync when not using the hand controller. Everytime SGP does a plate solve its syncs which would be converted to a recal, but what about the initial plate solve? Would that automatically be a sync?

Any chance the time zone offset has the wrong sign?

The other night I tried to slew my mount to my imaging target and the mount unexpectedly went the wrong way. Nothing happened as I was there to stop the slew, but I would like to understand why. The date, time, lat/long were all correct. I assume its an issue with syncing.

My mount is permanently setup and polar aligned, so all I have to do it mount the telescope and plug in the computer to be ready for imaging. I use sequence generator pro to automate everything along with phd for autoguiding, and Cartes du ciel for planetarium. I do not use the hand controller.

This is my workflow:

1. Start up APCC, and initialize the mount
2. Connect SGP, Phd, CdC
3. slew to the object in CdC
4. Plate solve in SGP (which performs a sync) to frame the object (I have sync -> recal checked in ASCOM driver)
5. Start taking images
...

6. finish taking images
7. park the mount
8. disconnect CdC, Phd, SGP
9. close APCC
10. power off

so...

Do I need to uncheck the sync -> recal for the initial sync or is the first rcal automatically a sync?

How does one clear a sync and start over?

I did search the yahoo group and the manuals but couldn't find the answers.

Thanks!
Dave
