Dude, your 8th photo is CHAMP!!! Everything else is of course very good!

And I thought the EF24mm 1.4L isn't for astro?

I shot at f/2 (to eliminate some of the coma) with an 8 second exposure using ISO 2500.  The EF 24mm f/1.4L II was recommended to me by Canon for photographing the night sky, especially with Auroras.  I have not yet had the chance to test that out yet. But I suspect this lens will eventually be superseded with an obscenely expensive RF version before long.

The really strange thing about this lens is that it Vignettes quite stongly on the EOS Ra but not the EOS R6.  The EOS Ra is simply an EOS R with two modifications.  The vignetting on that camera makes no sense to me, and it's quite disappointing.  It can't be corrected and simply must be cropped.  Or another lens used instead.  Canon have not been able to explain why this happens and seem to think it might be "caused by the use of a lens adapter".  Yet the R6 uses the same adapter and lens with no vignette.  It's a bit puzzling to me.

EOS Ra with the same lens (unedited) showing hard vignetting, even without a filter or a lens hood on the lens.  Quite a mystery.
