Description

This is a nice collection of objects at the border of Cepheus and Cassiopeia, including:

- NGC 7822, the "Cosmic Question Mark" (left side of image), which also includes Sh2-171 (the Teddy Bear Nebula) in its center.
- Sh2-170, the Little Rosette Nebula (the "dot" of the Question Mark, center of image).
-CTB1/Abell 85, the Garlic Nebula, an ancient supernova remnant (right side of image).
- Phantom of the Opera Nebula, Sh2-173, an emission nebula (bottom-right).

After applying BlurXTerminator, I was surprised to see Abell 85 so clearly. I had planned on adding some broadband data, but thought the stars might overwhelm it.

I prefer this orientation, but added Version B, rotated, to give it more of a Question-feel .
