Slight colour adjustment and image flip makes for a more pleasing end result in my opinion:
Sh2-261 is also known as LBN 863, SIM 34 or Lower’s Nebula.
Lower's nebula (Sh2-261) is found on the outermost edge of our Milkyway between the Orion and Perseus arm. Sh2-261 is a large faint region of predominantly ionized hydrogen. The nebula is named after Harold and Charles Lower who discovered this nebula in 1939.
Embedded within Sh2-261 is LBN 862 and LBN 864. Also there are several dark nebulae in this field.
