Sh2-150 is the red emission nebula and appears to be part of the Cepheus bubble, the expanding ring of gas and dust surrounding the star cluster NGC7160 and Ceo OB2association. Vdb 154 is the blue reflection nebula just left of Sh2-150, and the fan shaped reflection nebula just above Sh2-150 is RNO142. Mid upper right is Sh2-145, upper right corner is part of Sh2-140. A close-up image of Sh2-150 was done in 2021.
