This incredible beautiful set of data from IRSA / ZTF retrieval system https://irsa.ipac.caltech.edu/frontpage/ allows me to a second post-production attempt focused about Neowise comet of 2020.
I still cannot get rid of comet registration alignment by PixInSight, thus just played a hand allineation or R(zr) G(zg) and B(zi) channels in photohop of comet starless image, and then adding stars as new layer in “screen” blending mode.
After some research about Palomar 48 inches Samuel Oschin Schmidt telescope and ZTF camera I found here : https://www.ztf.caltech.edu/ztf-camera.html
and especially here : https://iopscience.iop.org/article/10.1088/1538-3873/ab4ca2/pdf
[ https://doi.org/10.1088/1538-3873/ab4ca2 ]
all data necessary for letting PixInsight plate solving and annotates final image.
Apart of aesthetic results, what is important is that if pixinsight works in annotation after platesolving, I hypothesize it could works also in comet registration after a proper platesolving of single channels masterframe; I’m going to try asap.
