Details:
Comet ZTF was observed scattered to broken cirrus clouds after moonset. Comet ZTF continues to lose its anti-tail although it is still noticeable in long duration images. The cropped image at left was taken with a Nikon d7100, Nikkor 180mm f/2.8 @ f/2.8, exp 5x120s, iso 3200, fixed comet and stars; the right image in the panel is an invert of the center without stars (57x100s or ~1.6 hours integrated time). All images post-processed with PixInsight.
Under dark moonless skies, the naked eye visibility was about the same as 24 hours earlier. I'd estimate the magnitude of the comet at +5.3. The left image was only 5 subs before comet drift became noticeable (3 mins integrated time).
Bortle 4, sky transparency 8/10, temperature 34F, RH 50%, calm winds. Orion Sirius EQ Mount used.
Skies are expected to be clear Sunday and Monday mornings before clouds return of southeast Arizona.
