Not exactly sure what's caused the odd star spikes in the image. it's not comet tails from coma I don't think - stars are perfectly round across the field when out of focus, and in other exposures I've done don't show this distortion. Across this exposure the spike is always the same (direction and proportional length) across the stars in the FOV< not like you see with coma and them trailing towards the edges... from my experience. I need to do some more tests, see if it occurs in other imags or if there was just something in front of the telescope for those exposures.
