That's why someone invented 24" Cassegrainian bifocals. :)

Wonder what the exposure length was.

I think you can only get colors like this in a composite using RGB filters. This was probably Hubble. A 24” would get pretty close, though, if you have a few thousand bucks just lying around.

More than the exposure length is the number of images. Typically thousands of images are stacked to produce a single photo. Each are filtered and false-colored to give the image we finally see.
