Nope, I havenât progressed far enough to use deconvolution yet. I did
download âPSFImageâ the other day to try deconvolution as my stars a
bloated in a bunch of my images.
Iâm experimenting with running ImageIntegration by hand on the registered G
subs. So far, I canât reproduce the that hole. I have reproduced the one in
all three components using Winsorized Sigma Clipping. If I turn âClip low
rangeâ, it cuts that star in half, with the left side black and the right
side normal.
If I use âLinear Fit clippingâ instead, the crud goes away!

I canât reproduce the parameters BPP is using to produce the holes. :-(

Mike,
Did you do deconvolution? This looks like dark rings that can be caused by
deconvolution. I think there is a global dark setting you can raise or lower
(forget which) to help with this. It also helps to have a star mask when you
do deconvolution.
Thanks,
Bernard

Subject: [AZ-Observing] Fungus eating the stars?
The other night, I was imaging the Trifid Nebula. When I processed the subs
in PixInsight, a bunch of the stars had this crud on them:

Anyone have any idea of what weird processing error on my part is causing
mess?
