I have accurate focus positions set in the equipment profile and at various times I have enabled / disabled the focus shift on filter change as I compare different approaches.
My understanding is that when the filter changes, the focuser moves by the difference between filter focus positions (relative movement). I use a microtouch focuser with actual focus stepper values around 35,000. (I always have my focus module powered down to the 30,000 mark for consistency across my various telescope combinations to a fixed 40mm extension, so if anything gets out of sync, I can reproduce the exact focus extension.)
I’m not so clear on what should happen with the sequence start and especially compared with a manual filter or focus selection.
I sometimes A/F before I start a sequence to set up the guider and I have had an instance when the sequence started, SGP tried to move the focuser to 30,000-35,000- hitting the endstop. I’m sure this is not supposed to happen by design.
This is just a heads-up. I suspect this has something to do with the manual luminance filter selection is being treated differently to an initial sequence filter selection. I need to be able to reproduce the conditions that cause this issue and with logs etc. before making a more formal response to the team.
Right now, my question is, has anyone else seen something similar? I’m using 2.4 beta(2) but I have no data to say it is specific to this version.
