Messier 27 - (The Dumbell Nebula) Region

M27 The Dumbell Nebula (Messier 27) captured on October 23, 2014 at the Staunton River Star Party. Click on the image for a larger version.

A .TIF format version of the image stacked with Deep Sky Stacker (29 4:00 minute exposures, with one flat and one dark, Kappa-sigma stacking) with saturation increased by 30% and with the histogram stretched slightly in Deep Sky Stacker can be found here.  Note that the file is 47 Megabytes in size. 

A stacked, but otherwise unadjusted version of the above can be found here.  This is a large file as well. 

Messier 27 is a shell of material that is believed to have been ejected from a star approximately 1360 light-years from Earth. More information about this nebula can be found here.

Recording system: Canon 350D Digital Camera.
Exposure time: 29 x 4:00 minutes
Telescope: 9.25-inch SCT, guided with 50mm guide scope, QHY5 camera and PHD.  Twenty-nine images, one dark and one light stacked in Deep Sky Stacker; saturation increased by 30% and histogram lightly stretched in Deep Sky Stacker; Star Tools used to further stretch, color adjust and sharpen.  Final tweaking with curves in Photoshop.
