I got tired of looking at colorful pictures of emission nebulae, so here is a colorful star picture.

How much of these colors are real (stellar type) and how much is from CA? If it is just CA, the colors should disappear with a modern lens or APO, and gone with a mirror setup. Do they? Vega is rising in the East. This is your opportunity to see how colorful the stars are with your setup,

Cheers.

David:

Interesting writeup.

I have accidentally taken and processed series of defocused images. All but the faintest stars  tend to have magenta or cyan haloes, depending on  which side the focus was on, but the result is not visually pleasing.

Cheers,
