Hello all,
Is there a way to train Prism for temperature compensation for auto focusing? I would like to do a run of a change of +/- 5 degrees C over a course of say 60 minutes to ensure my focusing is working perfectly. I am not sure how it is doing right now. I typically do a manual focus run (I have noticed automated focusing to be way off for me, I need to figure out why that is the case) prior to starting an automated sequence run and then don't perform any more focusing for the night other than check the box which says "Temperature compensation managed by PRISM" on the "Focus" window.

If you tell PRISM what the actual temperature chance is in steps over how many degrees, I can manage this for you. However, if you have your driver do this, it is not advised to enter it in PRISM as well. As for refocus on temp change in the automatic observation, this function is not available at this time. It can be added to the todo list however. I will push this to Cyril.

Is it possible to have him take a look at option for auto-focusing at filter change? I prefer this to using offsets.
