Well, I ususally don't eed or take darks with the SXVR-M25C (and the manual suggests not important either, and can DEGRADE the result), so I don't even have a library of them.

I know all about hot pixels, but these same pixels do NOT show on ANY other image EXCEPT if I use Entropy Weighted Average as the stacking parameter. In my usual kappa-sigma median, none. In ALL the others, except Entropy (and Maximum) I get these RGB streaks.

I'll continue to probably NOT use darks and use kappa-sigma median, but just wondering what.why this occurs in Entropy/maximum - obviously because of the high tonal contrast with these settings?
