IC5146- The Cocoon Nebula

An interesting nebula in that it contains both emission nebula (red) and reflection nebula (blue).
On this image I used a Custom Scientific Clear IR-block filter to keep the stars from bloating due to IR and UV light which the refractor doesn't do as good a job of focusing.
