Backyard Nighttime Sky Over New Jersey.

I just arrived back home from a short trip to Florida and the night sky was clear. Comet C/2022 E3 (ZTF) is now visible in the early evening sky. Both the Stellina and Vespera telescope/cameras were used to capture images. The telescopes automatically track the motion of the stars in the sky while taking 10 second images. During the time of the observations (15-63 minutes), the comet is moving, creating a tail in the image. This motion can be viewed in the time-lapse video.
