Hi Sean, thank you for the reply.
Yes, I have tried to use ASICAP on my mac computer.
It does work but there are two issues with it that I addressed before, on this website.
1. ASICAP does not have the feature to save the images in TIFF format (I believe for 16bit RAW it is fits only).
2. In ASICAP whether previewing or saving in fits format, I cannot get a saved fits image debayered, where I can recover the colors in post processing. I have at least three different fits processing apps and none of them recover the colors.
I try to keep my post processing simple, with the OSC camera, and prefer not to use fits for those reasons.
