NGC 2023 – Horsehead and Flame Nebulae 01-06-16

That was a tough processing challenge working through all that light pollution to reveal the Horsehead and Flame nebulae. This is the best I could produce with my minimal knowledge of Pixinsight, switching between Harry’s Astroshed tutorials and scavenging online for other tips and tricks to editing DSLR images in PixInsight. I’m pretty pleased with this as it is hard to pull out much detail after removing light pollution without adding too much of that blotchy grainy noise in the background.

NGC 7023 – The Iris Nebula

In the constellation of Cepheus during the fall months you can find NGC 7023. The Iris Nebula is a large reflection nebula with an apparent magnitude of 6.8. This nebula is lit by the bright star SAO 19158 at a magnitude of 7. It lies in the Milky Way about 1300 light years away from our solar system, and has a radius of 3 light years making it 6 light years across.

Through the eyepiece of my 6” telescope from my light polluted skies this nebula was not visible. Upon further magnification of the central star it started to appear a bit fuzzy. In the field of view there was the one bright central star and multiple dim stars scattered lightly through the field.

NGC 281 – The Pacman Nebula

Within the constellation Cassiopeia at a distance of 9,200 light years from earth is NGC 281. This nebula is in the Perseus arm of our Milky Way galaxy and includes the star cluster IC 1590 which is formed from around 279 individual stars in and about the cluster. Due to the darker nebulous regions of the cluster it has been dubbed the Pacman Nebula after the video game character. Discovered in 1883 by E. E. Barnard who described it as a “large faint nebula.”

In a clear dark sky you should be able to spot this nebula with an amateur telescope. From my backyard I couldn’t make out the nebula no matter how dark adapted my eyes were.

IC 5070 – The Pelican Nebula

IC 5070 lies closely to the nebula NGC 7000 in the constellation, Cygnus. This large emission nebula looks like a pelican to some viewers which gives it its name, The Pelican Nebula. The Pelican lies close to the star Deneb, about 1800 light years from our solar system, and the dark space splitting IC 5070 and NGC 7000 is actually a dark nebula. The Pelican Nebula is an active star forming region that is highly studied due to it’s evolving gas clouds.

This nebula has an apparent magnitude of 8.0, but due to its large size it was not visible in my telescope from my back yard. I had to use the camera to try to center it the best I could for imaging.

This is 17 images at 5 minutes a piece, 22 dark frames, 22 flat frames, and 22 bias frames. Stacked in deep sky stacker and post processing in Photoshop. I personally don’t see a pelican in this nebula whether it’s my picture or one of the others out there online, but either way this is a huge and beautiful nebula.

NGC 6992 – The Eastern Veil Nebula

The brightest portion of the Easter Veil Nebula is the region of NGC 6992. This is just a small section of the entire Cygnus Loop. The Cygnus Loop consists of the Western Veil , Eastern Veil, and Pickering’s Triangle. Discovered on September 5, 1784 by William Herschel, he described the western end as ex extending through the star 52 Cygni and roughly 2 degrees in length. He also described the eastern veil as branching nebulosity stringing and coming together towards the southern end. This nebula is large, but relatively faint, and it is a supernova remnant. The source of the supernova is estimated between 5,000 and 8,000 years ago. The entire Cygnus Loop covers and area of 3 degrees in diameter with an estimated distance of 1,470 light years from Earth. Analysis by the Hubble Space Telescope indicate the presence of oxygen, sulfur, and hydrogen.

Through the eyepiece I couldn’t see the nebula, and even a 2 minute photo it was very faint and hard to spot. The 5 minute images brought out more of the nebula and showed hints of the blues tucked into the red. Maybe the ¾ moon played a roll in washing it out so it was hard to see in the eyepiece.
