Description

This image captures several objects located in the constellation of Cepheus at a declination of +65 degrees. The bright blue star at image center is magnitude 5.8 star 26 Cep. The bright red HII emission objects at lower right and upper left are Sh2-145 and Sh2-150, respectively. They are located about 3000 light years away.

Just above Sh2-150 is the reflection nebula vdB 154, which appears purplish because of the interplay between the reddish emission and the blue star reflection nebula.

Several dark nebulae are also visible. At top left is the dark dusty nebula LDN 1214, blocking out the majority of the stars behind it. Immediately below, and somewhat continuous with it, is LDN 1213. The dark swath to the lower left of the center of the image is LDN 1209.

Just right of Sh2-150 is the tiny white fan-shaped reflection nebula, RNO 142.
