green splotches on drizzled image, PixInsight

[EricW]

Hello all, for an image I processed recently I was getting strange green irregular patches on the image after processing with WBPS and using drizzle 2, but not when I did it without drizzle. Any ideas?

Very likely you don't have enough subs to stack or they're not dithered enough. Is this a mono or OSC?

Hi, 15 subs with OSC

15 subs is nowhere near enough, how many seconds was each acquisition? did you use a filter? Bortle class sky? Scope?
example images? Target?

[EricW]

In the case that caused the issues, 600 second subs, Askar 80phq, L-pro filter imaging M83, B 5 sky. As to the contention that it is not enough subs, similar sessions (admittedly using an L-ultimate filter) did not see the same effect, so just trying to understand it.

images and process used have you tired it with DSS? still not enough information

was it a moonlit night? were there street lights in that direction?
I'm asking all these questions because you are only providing information in drips and drabs
Seriously an example image will reveal more
