Mosaic of the Cygnus Region of the Milky Way

image

This is a mosaic of 18 separate panels taken through an H-Alpha filter with the Rokinon 135mm f2.0 lens piggy backed on the Celestron C11 telescope.  Each panel was produced by stacking 20 images comprised of 5 and 10 minute exposures.  The total exposure time was 45 hours.  The picture includes the Veil Nebula, North American Nebula, Pelican Nebula, Tulip Nebula, Propeller Nebula and the Crescent Nebula in the Constellation Cygnus.  Microsoft ICE was used to assemble the mosaic.  Other software that was used included Adobe Photoshop, Pixinsight, and Maxim DL.

PROPELLER NEBULA (DWB111)

The Propeller Nebula is a very faint emission nebula in Cygnus. This is a stacked group of 30 five minute exposures in H-Alpha and 30 five minute exposures in O3 for a total exposure time of five hours. It was taken through the Astro-Physics 130mm Starfire Refractor and the QSI 690wsg camera.
