PixInSight had some problem in platesolving because of peculiar fits header, thus also was impossible to perform image registration > comet registration. I thus worked just by star registration of the few subframes and then play an image integration for each filter: I assigned R channel to zr filter, G to zg and B to zi even I suspect other choose may be taken. After that I made starless and star version for each channel and integrate in pixinsight the starry master, and in photoshop the starless master handly stacking rgb comet.
I finally played some photoshop tricks for pixel fixing, framing, dust lanes enhancing, etc… I would like a more wider field of view for a next attempt, but I confess to me is simply exciting and so so funny to make post-production over these enormous scientific quality data from such powerful instruments! As when I play with JWST or Hubble data (cfr. https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html ) I’m simply totally stoked! Thanks again to Taras!!!
PixInSight workflow to get starless and star separated masters by Starnet2 from SHO channel combination integration, this latter used as luminance level; files not stretched hereby available:
Comet C-2022 E3 ZTF from Livorno, Bortle 6 degree suburban sky. Rare minutes of clear sky let me take about 10 subrafems of 60″ in LRGB between 4 and 6 a.m.. Very hard set to combine due to comet alignment shifting parameters. Postproduction PixInSight, StarXtermintator, Adobe Photoshop.
