Re: 1200 not taking SGP corrections

Ray Gralak

Bill is correct. Not only that, both Latitude and Longitude are incorrectly set to 0 at one point:

Power off the mount if it is not off already. Then power on the mount and run APCC . Watch APCC to make sure that it initializes the mount with the proper Lat/Long values. If something else initializes the mount first (e.g. the keypad?) you will not see APCC’s popup initialization window, and APCC will not set the mount’s latitude and longitude. You can check thevalues set in the mount on APCC’s Site tab.

Not sure this is causing your problem, but this warning entry is all over the place in the log:



Is your site information correct? If not, update it and reboot the mount and try again.

Plate solve corrections generated by SGP are not being made by my 1200. The plate solve may work as a blind solve or direct solve by PS2, the error is shown, but on the next try there is no change in the error. I tried a couple of different computers, thinking there might be some problem with the settings.
