Image Details:
WCS transformation ....... Linear
Projection ............... Gnomonic
Projection origin ........ [1389.478009 2184.035331] px -> [RA: 7 26 23.585 Dec: +80 25 14.68]
Resolution ............... 1.568 arcsec/px
Rotation ................. -6.128 deg
Reference system ......... ICRS
Observation start time ... 2022-05-25 04:58:22 UTC
Focal distance ........... 591.89 mm
Pixel size ............... 4.50 um
Field of view ............ 1d 12' 38.0" x 1d 54' 9.9"
Image center ............. RA: 7 26 23.569 Dec: +80 25 14.74
Image bounds:
top-left .............. RA: 7 39 48.233 Dec: +81 24 59.94
top-right ............. RA: 7 07 49.468 Dec: +81 16 24.47

As each mono image popped-up on the computer screen (Sequence Generator Pro), the two bright galaxies NGC 2336 (Upper) and IC 467 (lower) were highly structured and easily visible. I could barely see a hint of C/2021 O3 as I scoured several of preliminarily stretched frames. Very ghost like. Once debayered the contrasted green hue of the comet was easily visible. I could not detect a nucleus nor hint of a central concentration in any of the individual 60s frames.
