Last night my imaging run was wrecked by temperature change 18 down to 7 over a couple of hours,steel tube Mewlon210 with 4 X secondary mirror.
The scope is on a good mount controlled by Sidereal Servo controller 11..
The obvious thermal solution is to re-focus every half hour or so.
My question: how do you save the current pointing direction in Sitech and return to it after slewing to focus?
I can't find the answer in the Sitech manual, not that that means that it is not there.
