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.

Pelican Nebula – Enhanced Detail

According to Wikipedia:

“The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward.”

“Millions of years from now this nebula may no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.”

Compared to my previous versions of this nebula, it is a little easier to see the pelican on the left hand side of this image due to the wider field of view that is a characteristic of the Takahashi FSQ106EDXIII telescope. It was captured in narrowband filters with 20 Sulphur, 17 Hydrogen-Alpha, and 16 Oxygen stacked images mapped to Red, Green and Blue as in the Hubble Palette.

PELICAN NEBULA

With the improving weather I was able to finish this off. The benefits of longer exposures are starting to pay off. The image is a stacked composite of 90 five minute narrow band exposures taken through the Astro Physics 130MM Starfire refractor for a total exposure time of 7.5 hours. It was processed in Maxim DL and Photoshop.

PELICAN NEBULA – Work in Progress

Well, the weather is turning bad, so I don’t know when I will be able to add data to this narrow band photo of the Pelican Nebula. I would like to add a little more color and some more detail. So far I have stacked 10 five minute H-Alpha images and 10 five minute OIII images and the nebulosity is beginning to look interesting. These were taken with a QSI 690wsg camera through an Astro-Physics 130mm Starfire refractor.
