That's some pretty nasty CA there......All of those colors are simply due to a bad lens.

Yes, this 50 year old lens Nikkor 200mm Q f/4 lens, used at f/4. It has only four elements, and was corrected for only two colors, i.e. achromat.

The challenge I proposed to the readers is to take a picture of this area, with Vega at the center, with their own prime lenses in the 180-300 mm range, with enough exposure and stretching to make V=+15 stars visible, and see how much or how little color they are getting with more modern lenses.  Are any of them apochromats?

Try it, and enjoy the colorful stars.
