NGC2245, Matt Ponstein

NGC2245

This picture is of a fan-shaped nebula named NGC2245. It is a very bright nebula that contains a bright star that adds to its light. This is also known as LBN 904 and it is a class R. It glows brightly because the gas inside it is energized by the stars within it that have formed.

This nebula is a very bright one I needed to try to decrease the brightness around the nebula while trying to focus on the center of the nebula. The brightness extents out from the center making it stand out from the other stars surrounding it. The gas inside the fan-shaped nebula is re-energized by the stars embedded within it.
