Dealing with local light pollution (Patreon)

That's "Chinese Arch" in the above photo comparison. The arch is in a remote area that should under a Bortle Class 2 sky (pretty dark); however, the arch is also 4 miles away from a rocket motor plant that is spewing out a lot of light pollution. If you try to take a photo of the arch and the Milky Way with a single exposure, you're going to get the image on the left, with the ugly green and yellow light pollution.

That's a RAW single exposure, and the Milky Way isn't too bad, because you're looking into a Bortle Class 2 sky. To get the image on the right (taken a few minutes earlier), I had to take two other exposures earlier in the evening and blend them with the Milky Way exposure.

The PDF explains how this was done and also gives another method for controlling local light pollution.
