Sh2-74 is a small Hα nebula that can be found about 4.8 degrees northwest of δAql in the western part of the constellation.
It measures only about 3 arc minutes in size, but the tip of the large, faint Hα nebula spreading to the south appears brighter.
Additionally, streaks of unnumbered dark nebulae are visible extending towards the southwest.
Sh2-74 is one of the star-forming regions found within the Milky Way, estimated to be approximately 10,000 light-years away from Earth.
