To test the functioning of SG pro in multi-target mode, I created 2 targets (M45 and M81).
I selected autofocus at each start sequence. At the end of the second target, I programmed the Park position of the scope.
For the automatic realization of flats after M45 and M81, I created a third target (leaving the coordinates to zero). To this target, the event was preceded by the ignition of the flat panel by a VBS script. At the end of the sequence, another VBS script allows the extinction of panel flats
I launched the sequence and overall, everything went well. There is just a small problem with the autofocus. For M45, there are many stars, the V curve was well done and the point of focus was good. By cons, for M81, there are few stars around the galaxy, and SG Pro finally set wrong focus. The curve of HFR was a real zigzag.
At present, Autofocus is programmed bin1 mode, with a duration of 5 seconds. In the few cases I have tested, everything was fine, except for M81!
What are the good practices to use in this situation? Increase the duration of the shooting? Switch to bin2 or more? Use darks?
Thanks for your advices.
