Description

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.C2020F3-Neowise-IRAS-24072020-starless.jpgI 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 Prystavski !!!
