Interesting wispy object
There's some ringing around the stars over the nebulous stuff, did you use deconvolution?

[RICH-DSO]

Yes, I did and perhaps I should not.

If I reduce the size of the mask option to 1 pixel, the rings somewhat dissapear. My bad!

[happy-kat]

It is a great module but I find I need to use it with care

I take note of your great comment. Thank you.
