Sh2-79 is one of the larger nebula in Aquila and has some nice structure that picks up very well when using the hydrogen-alpha filter. The wide field RGB filters do not do anywhere as well so you need a lot of exposure to pick up good color for the HA-RGB image. There is a very bright area that a larger telescope can pick up and revel nice fine detail. There is a lot of nebula around this object using a wider field of view telescope. I did not pick up any oxygen III so a narrow band color image will not work well here.

The very faint nebula in the image may be ionised by the B 2.5V class star [F89b] S79 1. 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.

Avedisova combines Sh 2-79 and W51C in the star formation region SFR 48.96-0.55 along with four infrared sources.
