The Skull & Crossbones Nebula is an active star-forming region approximately 20,000 light years away.

The Vela Supernova Remnant is an expanding bubble of ionized gas 800 light years away, caused by a supernova explosion 12000 years ago. This image is a small section of the bubble, presented as a narrowband combination of light emitted by Hydrogen alpha, Sulfur II and Oxygen III.

The Seagull Nebula a region of nebulosity that lies 1820 light years away, along the border between the constellations Monoceros and Canis Major. It includes the neighboring regions of star clusters, dust clouds and reflection nebulae centered around IC 2177.

Almost everyone has a go at imaging the Trifid nebula, which is composed of 3 different type of nebulae; emission, reflection, and absorption. When I noticed some faint red glow in the background, I decided to try integrating some long hydrogen emission line frames to see if I could get any structure out of it. I'm quite happy with the resulting background structures!

The Lagoon Nebula is an active stellar nursery spanning 60 light years across. This false color photograph shows the interplay of three gasses: hydrogen-alpha in green, sulfur-II in red, and oxygen-III in blue.

Shaped like a cats paw, NGC 6334 is a stellar nursery and emission nebula 5,500 light years away in the constellation Scorpius. This image comprises of emission line data for Sulfur-II, Hydrogen-alpha and Oxygen-III, mapped to red, green, and blue respectively.

The Gabriela Mistral Nebula lies close to the Carina Nebula ~7500 light years distant in the far-southern sky. This image is a narrowband representation showing glowing ionised gasses, Hydrogen-alpha (orange), Sulfur-II (red), and Oxygen-III (blue).

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.

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.
