North is up in this image.  NGC 7419 is the star cluster in the lower left. Sharpless 154 is the red emission region in the upper right. The color of the emission nebula. (Sharpless 154) is typical of such objects  where hydrogen gas is energized by nearby stars causing the gas to glow. The star cluster  (NGC 7419) is characterized as a young cluster of about 25 million years of age. We se it somewhat reddened due to intervening galactic dust. NGC 7419 is about 4,500 light years distant from Earth  Horizontal FOV is 55'

Image center is approximately - Equatorial 2000: RA: 22h 52m 45s Dec: +6100'19"
