with 8" f/3.9 Astrograph in Happy Jack
Uploaded 7/16/16

The blue portion of the nebula representing the reflection nebulosity wraps all around the pink hydrogen alpha component composed primarily of gas and dust combined. The field is filled with tendrils of dark nebulosity as well and the region is highly obscured from the dust laden central part of our Galaxy.
