Nikkor 105mm f1.4 attached to Nikon D750 body on Kenko sky memo
On a bitter cold mountain site, after moonset around 5 a.m, a small window time before sunrise was created for observing and photographing the green comet, i.e. comet C/2022 E3 (ZTF). The comet resembled a beautiful faint fan shape with the naked eye. To capture the color and fine details of the comet structure, I used the fast prime Nikkor 105mm f1.4 on a tracker to capture 70 short exposures. 70*13 sec exposures at ISO2000 finally edited in DSS and PS for the final image.
