Comments: This image shows the great diversity of celestial objects in the region of M8. These include the emission nebulae M8, M20, IC4685 and IC1274. Reflection nebulae are also seen in M20, IC1274-5, vdB 115, IC 4678. M21 open cluster is also seen. Many of the nebulae seen here are not often imaged do to their low surface brightness. Of note is the bluish halo surrounding and encompassing M8 itself. This appears to not be cataloged according to SIMBAD. It may be just a portion of M8 itself that is usually not seen. I purposefully left the background bright so to see this nebula.
