Hi Robin,

I just noticed that you've added a fix in version 4.1.12180 to exclude outlier pixels when creating the master dark - thanks. I will try it out as soon as I have a chance. I think I have at least one H-alpha target left that is still visible early after it gets dark enough to try it on.

Update: A couple of nights ago I created fresh master darks and used 3 different master darks across two cameras, including for 30 sec H-alpha subs with the Apollo-M Mini. The good news is that I could not see any indication of the spurious hot pixels in my calibrated lights with any of the master darks. I'll continue to monitor, but it certainly looks like the fix is working. Many thanks.
