Beautiful photos, Larry! Having a scenic foreground really helps. Out here I have light pollution and wind turbines for a foreground. Not pretty.
Skyglow can be a problem and DSLRs are very adept at picking up any green in the sky. 50% of their pixels are green sensitive (RGGB), to mimic the colour sensitivity of the human eye in daylight. For night photography, though, that can become a massive pain to deal with.
