Details:
Comet ZTF was observed under clear skies but with patchy airglow and is now moving ~15.6 arcmin/hour (the moon's diameter in just under 2 hours) at its most northerly point in its orbit. Comet ZTF anti-tail is now a broad area of dust that is very noticeable in longer duration images. The cropped image at left was taken with a Nikon d7100, Nikkor 180mm f/2.8 @ f/2.8, exp 5x90s (integrated time of 7.5 minutes), iso 2200, fixed stars; the right image in the panel is an invert of the center without stars (119x90s or ~3 hours integrated time). All images post-processed with PixInsight.
The naked eye visibility was definitely brighter than 24 hours. I'd estimate the magnitude of the comet at +5.0. I was able to image the comet at an iso 2200 with similar results to the one yesterday at iso 3200. The left image was only 5 subs before comet drift became noticeable.
Bortle 4, sky transparency 9/10, temperature 34F, RH 75%, slight breeze. Orion Sirius EQ Mount used.
Remarks: This was my 11th out of 12th morning recording the comet. I missed 23 Jan due to clouds.
My website contains time lapse movements of the comet.
