That's perfect Mike -
the rainbow colours but not split into 2 lines or looking like a piece of twisted rope.
OK - you've solved it -
I must have been slightly out of focus.
I will be able to check this next time after using a Bahtinov mask.
Me or anyone else watching this thread should now have a way of double checking the focus
before making a run of subframes.
It showed up on any of the RGB frames.
I hope to get even sharper pictures now.
