I use an EQ6-R-Pro permanently mounted in a sliding roof observatory in the UK. When imaging objects in Orion I need to be able to initiate a manual pier flip at least 30-45 mins before it reaches the meridian, due to the walls of the observatory blocking the guidescope FOV, plus obstructions on the southern aspect of my observing site. The ‘run manual pier flip’ button is permanently greyed out no matter what I do. I know some mounts don’t allow flip before the meridian but I’m sure this one does - previously when I used a fairly ancient laptop it seemed to work ok, but since changing to a new PC I seem to have lost this option. As far as I can tell I kept the settings the same, but I assume I must be missing something fairly basic in the settings of either SGP or EQMOD/ASCOM.
Can anybody who uses this mount force a meridian flip early if they need to? Does anyone have any ideas how I can re-enable this function? I can’t see that this precise question has been posted & answered elsewhere - apologies if it has. Thanks in anticipation.
