M78, an emission nebula in Orion.
This image is a stack of 30 one minute exposures using a 6" f/5 Schmidt-Newtonian telescope.
The exposures were calibrated and stacked and a gradient correction was applied using AIP4WIN.
The gradient correction was necessary due to interference from the rising gibbous moon.
