About this image

This is a stack of frames taken during the eclipse with the intention of detecting C/2020 S3 but it also picked up the SOHO sungrazer, C/2020 X3. The background has been removed using a median subtract with radius 20 pixels. It goes down to around mag 7 close to the Sun. The long axis is around 22 deg and S is approximately up. C/2020 S3 is the normal green colour due to CN but C/2020 X3 is yellow probably due to sodium emission as the comet is vapourised by the sun.
