The Trifid Nebula in Sagittarius
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.
