Description

I still cannot get rid of comet registration alignment by PixInSight of data retrieved from IRSA/ZTF archive, thus just played a hand allineation or R(zr) G(zg) and B(zi) channels in photoshop 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.

Thanks again and again to @Taras Prystavski  !!!
