Hi Ken,
Equipment can go till about 7 below meridian.
But in one of the ealier posts, we learned that the mount will only pier flip prior to meridian. That seems unlogical, but it seems to be a true statement. That is why we use -5min.
Tonight the pier flip did work again. We are not sure why. Possibly because we declined in the SGP settings an external control. Or because we terminated the link to the planetarium program. We will try again to be sure it doesn't again work just once. We could not really good read gunnys screenshots as the resolution was low.
Best regards,
Anna
