Sh2-150 in Hα

Orientation: North is to the right and east is up. Click for full-screen view.

The image shows the rather exactly north-south oriented emission nebula Sh2-150 that is acompanied by the reflection nebula vdB 154 (to the right in this image) and some surrounding dark and bright nebulae. Sharpless 150 is ionized by two stars - 26 Cep and HD 213405 - the brightest stars below the nebula in this image. Another Sharpless object (Sh2-145) is partially in this field in the lower left. There are several dark nebulae in this field - LDN 1206, 1207, 1208, 1209, 1214.

This nebula complex is located about 2,900 light years distant in the constellation Cepheus.
