Glenn,

|  RE: chromatic distortion in M20 image:  I think you're
|  viewing atmospheric
|  abberation.  Considering the low altitude of M20 from MI, it's highly
|  likely.  Phillip Perkins and I had a discussion on the APML
|  about his Trifid
|  image he posted a while back (as I had noticed the same
|  distortion in his
|  image).

I visited his site and do see the same distortion in his M20 image, although
not as bad.. I think you are correct regarding the atmosphere - I've looked
at other shots of mine of object at higher altitude, and the distortion is
far less pronounced.

Thanks for the Registar tips, and the Venus example..

Regards,
Dave
