Title

Naked eye comet 2023 A3 with Anti-tail

About this image

Clear sky much awaited, but Moon light strong. Not seen for sure by eye, but definite in 10x50bs once swept up. I used the camera to locate the comet clearly. Observing period 1915 - 1945 BST. The image is from 10 frames added in DSS. I used AstroArt to remove the blue background gradient. So a little "artificial".

Pleased to record the anti-tail. Overall tail length approaching 10 degress across the frame.
