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.

Black Eye Galaxy -M64

From Wikipedia:

“The Black Eye Galaxy (also called Evil Eye Galaxy; designated Messier 64, M64, or NGC 4826) was discovered by Edward Pigott in March 1779, and independently by Johann Elert Bode in April of the same year, as well as by Charles Messier in 1780. It has a spectacular dark band of absorbing dust in front of the galaxy’s bright nucleus, giving rise to its nicknames of the “Black Eye” or “Evil Eye” galaxy. M64 is well known among amateur astronomers because of its appearance in small telescopes. It is a spiral galaxy in the Coma Berenices constellation.”

This was taken through the Celestron EdgeHD 11 inch telescope.  A total of 138 images were stacked for a total imaging time of 7.5 hours

The subexposures for this stacked image were taken with LRGB filters.  The total exposure time was about 25 hours with the Celestron 11 inch telescope.

From Wikipedia:

“The Whirlpool Galaxy, also known as Messier 51a, M51a, or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way, but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.”
