Comet ZTF E3
in the morning sky
1/24/23

Now the Earth is at orbital plane crossing, the anti-tail can be clearly seen pointing to the left in this 3 degree wide field. The gas tail is more bluish today as seen on the right and lays over the yellow/amber colored dust fan.

This is the first shot we have taken with our new Williams Optics Zenithstar 81, using a televue 0.8x coma corrector. It was very cold this morning and snowed all night long. A clearing at 2am and we shoveled snow off the observatory and rolled it back for this image. An hour later, all the optics had sheets of ice on them.
