Very interesting Matk. I don't use anything but a Baader Neodynium filter however I get a doughnut shape on flats. Never used to so I think its reflections in the scope, I have repainted the OTA and every screw and nut and just need a dark clear night to collimate and test it out properly.

On a slightly different subject but related to your camera, have you seen this thread concerning a weird background effect in the red channel:

Chat / Re: Great Rainbow this evening.

Thanks for that Mark, I found the second link easier to understand.

I did know that each person is seeing their own Rainbow, I think I learnt that possibly at school but I never learnt about Alexander's dark band.  I knew there must be a scientific explanation for it as it always seems to happen.
