Just starting to move to narrow band imaging and initial testing shows that focusing with the NB filters is probably going to be slow. So, I am thinking that I want to always focus using the luminance filter binned and then have SGP make a relative adjustment for each NB filter. I have an accurate focus position for all four of the filters defined in the filter setup dialog box. These were all done at 24.1 C. These are the options chosen in the Auto Focus Options:
I have also selected “Auto adjust focus per filter”
It kind of seems like some of these options might be mutually exclusive but I would like to verify that I have chosen correctly. When I tested this configuration Friday night, I did not get a good focus with the NB filters but there could be other causes for that.
