About this Image

Cederblad 214 and NGC 7822 (also named SH2-187) are a nice but different pair of emission nebulae. Ced 214 shows a very turbulent structure with obscuring dust and glowing pillows blown away from the stellar wind. NGC7822 more reminds of the North american or California nebula showing a "wall" in the center.
North is right.
