Not sure what this green dot could be. Artefact? Something more exotic like a supernova? It is not there on all exposures and is very faint. Nothing in SIMBAD. Green dot more clear here.
I think I see it in all the r-band exposures where I’d expect to (some are blurrier than others and it isn’t discernible) – are you seeing something different? I didn’t look too too carefully.
I might be blind to be honest. It is pretty blurry and my eyesight isn’t great
I think it’s not an artifact and is a galaxy behind this galaxy.
ah cheers
