The Great Andromeda Galaxy

 

Really happy with this outcome. This was a tougher object to process so it is especially rewarding.

The Cygnus Wall

The Cygnus Wall

Here is a wonderful section of Nebulosity in Cygnus. This is the Cygnus Wall which is part of the North America Nebula. This wall is actually a region of star formation. This cosmic ridge spans about 20 light-years and lies about 1,500 light years away.

The wide field view picture contains both the North America Nebula and the Pelican Nebula which I took earlier in May.

Where it is in the North America Nebula

Starless Version

Elephant Trunk Nebula (Sh2-131)

Sh2-131

This was night 5 of a run of clear nights. VERY unusual in Illinois to say the least. Very happy that I can automate the capturing. SO, here is the Elephant Trunk Nebula or Sh2-131 from the Sharpless Catalog of Emission Nebula.

The Elephant Trunk Nebula winds through the emission nebula IC 1396, in the constellation of Cepheus. IC 1396 is a young star cluster.

The 'cosmic' elephant's trunk is over 20 light-years long!

The Lion Nebula, (Sh2-132)

The Lion Nebula

The Lion Nebula, or Sh2-132 has an extended emission nebula visible in the constellation of Cepheus. My picture captures the mane and body but not the tail. That will be another day. It is located on the southern edge of Cepheus, at a distance of almost 10,400 light years.

A Quick Take on the Crescent Nebula

So while waiting for the Eastern Veil to rise last night above my roof line, I took this easy pickings object... The Crescent Nebula.

It formed by the fast stellar wind from the Wolf-Rayet star WR 136 (Bright star in the middle) colliding with and energizing the slower moving wind ejected by the star when it became a red giant.

18 minutes of 6 stacked, 3 minute exposures.

Sharpless 2-121

Sharpless Catalog 2-171

Sharpless Catalog 2-171, is a star forming nebula located in the constellation Cepheus, ~3,000 light years from the Earth.  A very young cluster of stars known as Berkeley 59, is located in the lower center right of the image.

Pelican Nebula with Optolong L-Enhance Filter

The Pelican Nebula has been on my bucket list since I've been in my 20s. I'm delighted to have finally captured it! 

The Pelican is an emission nebula close to the bright star Deneb in Cygnus, the Swan. Named for its resemblance to a pelican, (although my wife says it looks like a pterodactyl!) the nebula is associated with the neighboring North America Nebula.  It is a particularly active mix of star formation and evolving gas clouds.

M52 and the Bubble Nebula

Open Cluster M52 and the Bubble Nebula.

"To the eye, this cosmic composition nicely balances the Bubble Nebula at the upper right with open star cluster M52. The pair would be lopsided on other scales, though. Embedded in a complex of interstellar dust and gas and blown by the winds from a single, massive O-type star, the Bubble Nebula (aka NGC 7635) is a mere 10 light-years wide. On the other hand, M52 is a rich open cluster of around a thousand stars. The cluster is about 25 light-years across. Seen toward the northern boundary of Cassiopeia, distance estimates for the Bubble Nebula and associated cloud complex are around 11,000 light-years, while star cluster M52 lies nearly 5,000 light-years away."

The Fireworks Galaxy and an Open Cluster

NGC 6946, or "The Fireworks Galaxy", is one of a ~dozen nearby neighbors to the Milky Way. The galaxy, is a 9th magnitude face-on spiral galaxy positioned on the border between Cepheus and Cygnus. 

At ~22.5 Million light-years it's one of the nearest galaxies outside of the Local Group. In the past 100 years, 9 supernovae have been observed in NGC 6946, hence the nickname the Fireworks Galaxy!

I so enjoy capturing photons from two different objects and this photo contains a lovely open cluster, NGC 6939. Discovered by William Herschel in 1798, it contains some ~630 stars. With the use of photometric studies, the age of the cluster was estimated to be between 1,0 and 1,3 billion years

The Fireworks Galaxy and Open Cluster NGC 6939

This is one of my favorite photos even though it could use another hour of data. I may go back and add some to it.
