A nice flat field and round stars corner to corner which is rare for lens full frame longer focal length. A reasonable amount of detail for a lens image.
I may end up getting my EOS R modded as I have wanted to have a full frame modded digital camera for a while now. Its just a bit too good for regular photography to do that even though I have a Sony A7riii as well.
But I am tempted especially with Milky Way season coming up.
The red halo is odd but probably easy enough to process out so long as it not too common. Like you said its probably some reflection artefact from the modded filter.
I was using 5 minute ISO640 for deep sky objects at a dark site which seemed to work well.
EOS R sweet spot for ISO is higher than the Sony's, around 1600 or so. ISO2500 is game for urban imaging.
Greg.
