Notes

vdB 153 is a small blue reflection nebula in the constellation Cepheus. It appears as faint diffuse nebula around the blue star TYC 4268-166-1.

Sh2-140 is an H II region and part of the Cepheus Bubble, the expanding shell of gas and dust surrounding the Cep OB2 association. Sh 2-140 is illuminated and ionized by the star HD 211880. HD 211880 is a member of the young open star cluster Pismis-Moreno 1 and creates the bright ionization front separating Sh 2-140 and the molecular cloud LDN 1204.
