Comet ZTF E3
in the morning sky

 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.
