Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

IC 1795 - The Fish Head Nebula in SHO

IC 1795, also know as the Fish Head Nebula, is an area of new star formation with glowing gas and dust, in the constellation of Cassiopeia. It is actually a portion of the larger Heart Nebula complex (IC 1805) that is located about 6000 light-years from earth. Since my scope cannot fit the entire Heart nebula into its field of view, I opted to frame just the fish head portion of the nebula. This was to be shot with my Mono camera and narrowband filters so that I could get the Hubble Palette colors that I am quite fond of.

NGC 7635 - The Bubble Nebula in SHO

NGC7635 - The Bubble Nebula - A narrowband image in the Hubble Palette. Also known as Sharpless 162 and Caldwell 11. The Bubble Nebula can be found in the constellation Cassiopeia, not far from the Open Cluster Messier 52. This area is a rich HII region and the bubble itself was created by stellar winds from a massive hot blue Wolf-Rayet star, AO 20575, that shed its material about 300,000 years ago to form the bubble. This star is 44 times larger than our sun. The Bubble itself is found in a massive molecular cloud that contains the expansion of the bubble and is excited by the same star, causing it to glow as well.

NGC 7380 - The Wizard Nebula - in Hubble Palette with Mixed Narrowband and RGB Filters

NGC 7380, Also known as the Wizard Nebula, the Flying Horse Nebula, and Sh2-142, is a gas, dust, and young star region. Located 7200 light-years away in the constellation Cepheus, the Wizard Nebula is tough to see visually but is a favorite imaging target. Most people have no trouble making out the Wizard - wearing a pointed hat, a well-defined nose, and a bright blue star for his eye. He also appears to be wearing a cloak and posing with his hands and fingers outstretched. FIrst complete Narrowband image attempted.

Messier 31 - The Andromeda Galaxy - with Neighbors M32 and M110

This is my second attempt at M31. With a larger focal length, I could not fit the whole galaxy in so I experimented with a framing that showed it’s two neighbors.

Messier 31 is also known as NGC 224 and the Andromeda Galaxy, or as the Andromeda Nebula before we knew what galaxies were. It can be seen by the naked eye in the constellation Andromeda (how appropriate!) and is our closest galactic neighbor located 2.5 Million light Years away. It is estimated that it contains abut one trillion stars - twice that of our own Milky Way.

NGC 7331 and Two Galaxy Groups: The Deer Lick and Stephen's Quintet

Hot off the presses from my photo session last night: NGC 7331 and Two Galaxy Groups: The Deer Lick and Stephen's Quintet.

There are plenty of star clusters out there, but I was interested in shooting a cluster of Galaxies. Stephen's Quintet is high enough this time of year to clears my trees about midnight, so I started to plan on capturing that. I soon realized that I could get two for the price, as The Deer Lick Galaxy group would fit in the same frame if I composed the shot well.

IC 5146 - The Cocoon Nebula

Located 4000 light-years from Earth, IC 5146 - better known as the Cocoon Nebula, is an area of both bright and dark nebulae in the constellation of Cygnus the Swan. The red portion is due to light shining from hydrogen emissions, while the blue portions of the nebula consist of dust reflecting the light young hot blue stars. At the core of the nebula is a bright star that only formed about 100,000 years ago. The shell of gas is about 15 light-years across. Also seen is a dark lane of dust that appears to project from the main nebula towards the west. This dark object is an obscuring cloud of dust known as Barnard 168. To me, it almost looks as if the dark cloud is emanating from and trailing the Crescent Nebula - I like the effect!

NGC 6992 - The Veil Nebula

NGC 6992, The Veil nebula, is a collection of hot gas and dust that forms a portion of a supernova remnant. Located 2400 light-years in the constellation of Cygnus, It forms one visible portion of the Cynus Loop - an expanding shockwave bubble from a star that went supernova between 10,000 and 20,000 years ago. The expanding gas from this explosion compressed Hydrogen, Oxygen, and Sodium, causing the formation of shockwaves and causing the colors you see here.
