Messier 27 (Dumbbell Nebula)

This is an object, I imaged several times during the years. The latest image is from a data set I obtained from the remote observatory Deep Sky West with telescopes in Chile and New Mexico. The image shows the planetary nebula Messier 27, located in the constellation Vulpecula.

Data calibration and registration and the final processing was done with PixInsight.
