This is a beautiful Ha region with little OIII except in the cores of the bright nebula and a couple very curious locations.
While processing I noticed a small "line" nebula and that started me down the rabbit hole to explore this image more carefully.
That line nebula turns out to be the cosmic jet from a new born star! Herbig-Haro Object 190!! In the neighborhood of it there are a lot of Young Stellar Objects (proto-stars and pre-main sequence stars), just babies!
Turning my attention to another OIII rich blob on the right of the image. Aladin and Vizier list it as an HII region (WISE G174.384-00.371). This object does not emit much in Hydrogen at all and was very bright in OIII. Potentially a mis-categorized PN??
But just below that blue blob there is a OII streak going down and to the left. That nebula is not listed anywhere I could find. If someone knows how to get an object confirmed that would be amazing and I could use the help. For now it seems like a OIII streak leading away from WISE G174.
In that same area is a nice reflection nebula, an eclipsing binary, as well as an Emission Line star!
