Gum 15 / RCW 32 Hydrogen Emission Nebula thumbnail
Gum 15 is a cloud of hydrogen gas 3,000 light-years from Earth. It is shaped by aggressive winds flowing from the stars within and around it.

Cone Nebula NGC2264 thumbnail
The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by the brightest star of NGC 2264. The faint nebula is approximately seven light-years long and is 2,700 light-years away from Earth.

Luminance vs H-alpha Filters thumbnail

The Unusually Shaped Red Rectangle Nebula - HD44179 thumbnail
The unusual shape of the Red Rectangle is likely due to a thick dust torus which pinches the otherwise spherical outflow into tip-touching cone shapes. Because we view the torus edge-on, the boundary edges of the cone shapes seem to form an X. The distinct rungs suggest the outflow occurs in fits and starts.

Animation of Lagoon Nebula Reprocessing Stages thumbnail
Often I like to see how an image is processed from start to finished. Presented in this animation are the main processing steps in sequence from my reprocessed image of the Lagoon Nebula.

Lagoon Nebula Reprocessed thumbnail
Cloudy nights and full moons gave me a chance to have another look at one of my first deep sky photographs. The first image taken through my telescope that made me say "wow". I decided to try reprocessing the original data with the skills I've learned in the past few months.

Horsehead Nebula in Hydrogen Alpha thumbnail
I decided to take advantage of the only clear night for over a week to play with some new toys: an Astronomik 6nm Hα filter, and a Starlight Xpress adaptive optics unit. After learning how to calibrate and use the AO, I settled on the Horsehead Nebula as my target.

Helix Nebula NGC7293 thumbnail
The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula located in the constellation Aquarius, 695 light years away.

Test Shot of the Orion Nebula thumbnail
My original target was the Helix Nebula, but after spending most of Saturday night trying to work out how to use off axis guiding, I gave up and noticed Orion was rising. A nice bright target to use the drift aligned mount on.

Barnard 72 - Snake Nebula thumbnail
I have only a few nights experience with astrophography, so while I wait for my new camera, I'm using my wife's full frame DSLR. Since it's not so sensitive to emission nebula, I thought I'd try a dark nebula.

Swan Nebula thumbnail

The Orion Nebula thumbnail
The Orion Nebula is one of the brightest nebulae in the sky, visible to the naked eye. It is seen as the fuzzy middle star in the sword of Orion. The nebula is 1344 light years away and is one of the closest star forming regions to Earth.

Eagle Nebula thumbnail
The Eagle Nebula is located 7000 light years away and is home to the famous "Pillars of Creation", shown in the centre of this image. This photograph is presented in the Hubble narrowband palette, which shows the distrubution of Hydrogen (green), Oxygen (blue), and Sulfur (red) gasses.

NGC 3199 thumbnail
NGC 3199 is a hydrogen emission nebula, about 12,000 light-years away. The nebula is about 75 light-years across with a Wolf-Rayet star generating an intense stellar wind in the center of its ring.
