M20 Trifid Nebula and friends in Sagittarius

M20 and M21 L(HaR)GB

Kind of wider view of the well known pair of M20 Trifid Nebula and M21 the open cluster just below and right of it in the constellation Sagittarius. This was taken at home with virtually a full moon. Surprised how much red Ha was around the area. I don't recall seeing a shot of the area with this much Ha.

Here's the area just with the Ha filter. Shows up the nebulosity with better contrast.
