Hi
I have been using asiair pro, asi533mc and ZWO EAF for some time and have generally been very happy with performance. Recently however I have started using Pixinsight and a different OSC workflow which involves splitting RGB channels and I was surprised and a little shocked to see that in all images where i have used autofocus, G and B are focused correctly but R is always noticeably out of focus. Note that I use an optolong L extreme dual band filter with osc.
I assume EAF does not use a debayered image when calculating the optimal focus? Is there any way this can be addressed in the software? Currently I need to let asiair calculate the autofocus and then apply an offset manually to get a better focus with the red channel but it is always trial and error and not a satisfactory solution.
