Yes, I'd love to be able to correct coma. My EF35/2 IS is a wonderful lens, but the poor coma renders it useless for landscape astrophotography.

LOL, yes, and that was brave of you to post that! I did the opposite when I first shot the moon. I spot-metered the moon and then set the manual exposure. Of course that turns white to middle gray, not really what you want, either. I think spot meter +1 EV works well as a starting place if I remember from my last shot.
2. Forgive my extreme ignorance on the subject, but I assume the so-called moon illusion that makes it appear larger near the horizon is just a psychological phenomenon, not something visible in-camera, right?
Yes, but the super moon is actually a bit larger, as the moon is a little closer to us.
Taken with my good old 17-40 and 50D.Nice photo.

I took a milky way shot and coma from city lights at the bottom edge (portrait format) was very noticeable.Is it possible for you to post this picture? I took a look at lenstip.com but I'm interested in a real life example of this coma issue at F2.0. That would really help in the decision I want to make.
