Comet 2022 E3 (ZTF) January 24, 2023 5:52am EST. Taken with my Askar 108 with reducer, focal length 420. It is now over 3 degrees wide. You wonder, why didn't I rotate the camera to get the comet in landscape to get even more of the tail. Well, I imaged 3 deep sky objects earlier, and when I did my flats at 2am they had some interference lines in them. I fell asleep knowing I could do the flats after the comet with a different light source. I had no idea the comet would span the entire short side of the chip!! So I was stuck, if I rotated the camera, the deep sky objects I did earlier would be a fail. So, had to go with the setup as it was. Haha, live and learn!
