Description

It's pretty busy in this region of the sky. :-) In the beginning I only wanted to take a few H-Alpha exposures to show the corresponding regions within the reflection nebula. Then I realized that there is still this large, very diffuse H-alpha region away from the Rosebud Nebula and enclosing the open star cluster NGC 7142.

This part of the sky offers enough variation for at least three images with its reflection nebula, star formation areas, dark nebulae and the open star cluster. It was a real surprise for me. Hope you like it!
