An attempt of astronomic photography postproduction using Gimp, made easy by excellent data quality retrieved from SPA-1-CCD Telescopelive network focused about NGC1333 and IC348.
Previous PixInSight processing made, generating an LRGB deconvoluted, denoised, starless/stars pre-elaboration, starless + 0,75% stars pixelmath integration before .tiff exporting and Gimp postprocessing.
Thanks to Taras Prystavski contribute on Astrobin forum ( https://www.astrobin.com/forum/c/group-forums/comets-imaging/c2020-f3-neowise-comet-raw-data-from-remote-hosting/ ) I retrieved from IRSA resource all available data from ZTF telescope focused about Neowise comet; cfr. IRSA / ZTF – https://irsa.ipac.caltech.edu/applications/ztf/?__action=layout.showDropDown&
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!!!
