Details:
Comet ZTF was observed under perfect skies after moonset. Comet ZTF continues to lose its anti-tail although it is still noticeable in long duration & high iso images to my surprise. The cropped image at left was taken with a Nikon d7100, Nikkor 180mm f/2.8 @ f/2.8, exp 3x90s, center 6x90s, and right 9x90s iso 3200, fixed comet but not stars. Obviously, this comet is moving very fast. All images post-processed with PixInsight.
The other panel shows:
The cropped image at left was taken with a Nikon d7100, Nikkor 180mm f/2.8 @ f/2.8, exp 173x90s (or 4.3 hours integrated time), iso 3200, fixed comet and no stars; the right image is its invert. 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 +5.2.
Bortle 4, sky transparency 10/10, temperature 35F, RH 45%, calm winds. Orion Sirius EQ Mount used.
