Image Details:

The Lagoon Nebula (M8) is 4,100 light years away. The radius is 55 x 20 lightyears. It’s one of the only two star-forming nebulae faintly visible to the eye, you can see it as a distinct cloud-like patch with a definite core with binoculars.I captured it from my driveway through my telescope using Sulphur, Hydrogen-Alpha and Oxygen filters
