FYI, I have done a very quick test as I am quite busy tonight, took a shot with precise focus and as usual red and blue are out of focus while green is sharp as.
I then miss focused by a smidgen and behold blue and red was in focus and green was out of focus. Apart from looking a bit green the star looked very symmetrical and there was no fringing either. This hold to the ability to use RGB and focus refocus for each colour.
Couldn't buy any RGB filters today though. I am though considering filtering the monitor to the individual colours and refocus not sure if it will work but could be a very low cost method.
I want to look at consideration of fitting a filter-wheel between the Canon and lense but that would be quite a chore.
Next step will be increase F/STOP and test that but for another night.
