RA: 7 15 30.913 Dec: +79 23 55.43 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.
