Brent which scope was that taken through? It shows the classic Achro colour effect I believe. I would agree it is probably slightly out of focus, the gas clouds should have much sharper definition. It might be that your getting some fogging in the camera or the IR Cut. If the sensor coverglass is fogging up it could produce that effect. My suggestion: dry the camera out completely (stick it out in the sun with everything opened up (battery compartment, memory card hatch, adaptor or filters off, take the back off if you want, etc)). Put it in a sealed container with some silicia moisture absorbing packs and leave it for a couple of days. Then seal it inside a ziplock bag with a cutout for the T-thread adaptor (see my Argon bag technique in Rowlands Cold Finger thread). Leave some moisture absorbing sachets in the ziplock bag. You don't need to use Argon to test but for long moist nights it works well. Do some test shots again and see if the fogging is still there. Just my 2 cents.
