Sh2-79
HaRGB - Emission Nebula in Aquila
Sharpless 79
Here is the H-Alpha channel only:
-----------------------
According to galaxymap.org "The very faint nebula in the image may be
ionised by the B 2.5V class star S79 Other sources state that at
least some of the visual emission in this direction may be associated
with the supernova remnant SNR G49.2-0.7 (also called W51C) which is
believed to be at a distance of 6 kpc."
