Description

M20 is also called NGC 6124, it locates in a H II region  of Sagittarius. It was first discovered by Charles Messier on 6/5/1764.  M20 is bright nebula, it is already very pretty with LRGB,  adding Ha really pops it out into another level. It is not a high in sky from Texas. It took me around 2 weeks to collect data.
