Details:
Comet ZTF was observed under near perfect skies and is now moving 9.8 arcmin/hour (the moon's diameter in just 3 hours). Comet ZTF is losing its anti-tail but is increasing length and brightness with its dust and ion tails (the ion tail is the bright narrow stream). The cropped image at left was taken with a Nikon d7100, Nikkor 180mm f/2.8 @ f/3.2, exp 6x105s, iso 3200, fixed comet and stars; the right image in the panel is an invert of the center without stars (64x105s or ~1.9 hours integrated time). All images post-processed with PixInsight.
Bortle 4, sky transparency 9/10, temperature 30F, RH 85%, calm winds. Orion Sirius EQ Mount used. I'd estimate the comet's brightness at +5.3 with the ion tail extending more than 5 degrees.
