It's not a good lens for this task wide open. Personally, I would not use it wide open in the starry night sky scenario. That may be because I like to be contrary, or because I know it's a bad idea with this lens. I don't think stopping it down would solve the issues this lens has at the edges of a full frame, but it might improve the odds for a better capture.

Why do you think stopping down wouldn't help? The very first post in this thread shows coma decreases when stopping down to f/2.0, and vanishes completely by f/2.8.

I'm talking about aberration (pick the correct type) in general, which is pronounced with this lens and doesn't go away even at f8 if an edge is distinctly sharp and contrast is high enough. I personally don't worry about the coma thing, since I don't photograph stars. And, I can see purple edges on the stars at f5.6 in the example. Maybe it's caused by my eye glasses.

Auroras are not bright stars on a black background, so I don't get the connection in this discussion, other than you use the lens at night. I can see the 24f/1.4L II being good for auroras, because they are soft and flowing without a lot of high contrast.

I've shot some auroras with the 24L/1.4 and later 24L/1.4 II, mostly stopped down to f/1.8. While the results are not perfect, they've been quite acceptable even up to 150 cm x 100 cm print size. Nobody except techie nerds ever took any notice of the slightly mangled stars in the corners because they were too busy at oohing and aahing at the aurora.

Kind regards,
