Hi folks,
We tried using temp comp today again. Did not work.
Find attached the respective log file.
My ability to read such a log file is limited, But when I look at the time around 3:10, I see that there is a temperature compensation step after saveing the other image:
[08.21.17 03:10:01.976][DEBUG] [Sequence Thread] Temp Compensation: Using focuser temp…
[08.21.17 03:10:01.977][DEBUG] [Sequence Thread] Temperature compensation: Adjusting for 0,2 degrees (end: 11,6; start: 11,4; coefficient: -50) for 9,7 steps…
further below, prioir to starting the next image, the filter is changed according to the values that we have set in the filter list in the evening at around 16,5°C
[08.21.17 03:10:02.285][DEBUG] [Sequence Thread] Adjust focuser pos per filter: Moving focsuer to focus position (70790)…

[08.21.17 03:10:02.285][DEBUG] [Sequence Thread] New filter: Red; Focus pos: 70790
[08.21.17 03:10:02.285][DEBUG] [Sequence Thread] Pos delta: 167 steps
[08.21.17 03:10:02.285][DEBUG] [Sequence Thread] New position-> (current: 70622) + (delta: 167) = 70789
[08.21.17 03:10:02.285][DEBUG] [Sequence Thread] Focuser moving to 70789
[08.21.17 03:10:03.009][DEBUG] [Sequence Thread] Focuser move call complete
[08.21.17 03:10:03.509][DEBUG] [Sequence Thread] Focuser position matches requested position (70789), continuing…
this leads to a change in focus position from only one step in comparison to the starting value: 70790 in filter list to 70789 as current position. But temperature dropped around 5 degree during the night.
I just can not understand, what SGP is doing there. From our settings, he should move -50 seps/degree, so over all, with a 5 degree change the focuser postion should have moved 50X5 steps, and not just one stpe.
Can someone explain the issue?
Thanks and best regards,
Anna
