This is a Hubble palette narrowband of the area known as the North America Nebula (NGC 7000) and the Pelican Nebula (IC 5070). It is a very large emission nebula complex in Cygnus, though too dim to see with the unaided eye.  NGC 7000 (to the left) gets its common moniker for obvious reasons, especially the “Mexico” portion, also known as the Cygnus wall.  It might be more difficult to perceive why IC 5070 is known as the Pelican Nebula — can you “see” it?

Technical details as follows:

Takahashi FSQ 106N and SBIG STL11K mounted on a Paramount MYT from MYHY Observatory in the Philadelphia suburbs. About 40 hours of data split between Ha, OIII, and SII filters collected in 2008, 2014, and 2018, respectively. All exposures are 30 minutes in duration and unbinned. Calibration was in Maxim, alignment/integration in PixInsight, and all other processing in Photoshop.
