There were some issues with blobby stars at both ends of the spectrum and increased background brightness but the biggest problems were some really spectacular reflections.
I see, definitely a huge hit to image aesthetics. I've managed to find a decent UV/IR cut threaded filter, hopefully this will do the trick!

Thank you for your help
