Apart from its common red color (the stimulated interplanetary dust has a specific light spectrum: most of the red is produced from Hι〠[N2]〠[S2] and a small amount of aquamarinc is produced from [O3]〠Hβ), the light blue background is part of the reflection nebula. The enhancement of the emission nebula gives the M20 its rich color and makes it stand out among its various counterparts in the Milky Way.

Taken at Cuifeng, Hehuanshan in July 2014, using William Optics WO Megrez120 f/7.5 refracting telescope + Canon EOS 350D camera (customized UV/IR cut photo filter), ISO-1600, total exposure time: 1 hour 24 minutes (single exposure 3.5 minutes). Takahashi EM-200B equatorial mount was used for tracking. Reduction of voltage bias, dark current and flat field adjustments were done in DeepSkyStacker. Additional retouching was done in Photoshop.
