Gabriela Mistral Nebula thumbnail
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).

Waves of Vela thumbnail
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.

Rosette Nebula thumbnail
The Rosette Nebula is an emission nebula 3000 light years away. The central area of the nebula contains an open cluster of hot, blue stars which have cleared much of the center of its gas.

South of Orion - NGC1999 thumbnail
NGC 1999 is a dusty blue reflection nebula, embedded in the hydrogen dust cloud of Orion. This narrow band enhanced image shows the light blue NGC 1999 at the center, with the edge of M42 (the Orion Nebula) at the far right. Also shown in the image is the waterfall nebula, the magenta shock wave between NGC 1999 and M42.

Nebula Sh2-37 thumbnail
Sh2-37 is a hydrogen emission nebula with two small blue reflection nebulae, embedded in a dusty background against the core of the Milky Way.

Saturn Nebula thumbnail
After a brief hiatus from astronomy to build a new, larger observatory, I've chosen another difficult target that was surprisingly bright.

IC4603 and IC4604 Showing Rho Ophiuchi Color Transition thumbnail
Inside the Rho Ophiuchi cloud complex live the star clusters IC4604 (left) and IC4603 (right). Heading towards the bottom of the image shows the transition from blue reflection nebulae to red emission nebulae. Interspersed are dark absorption nebulae, blocking the light from the stars behind them.

Seagull Nebula thumbnail
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.

The Flame and Horsehead Nebulae thumbnail
Adjacent to the bright blue supergiant star Alnitak shines the ionised hydrogen of the Flame and Horsehead nebulae.

On the Shoreline of the Lagoon thumbnail
Next to the Lagoon Nebula, there lies the often overlooked collection of absorption, reflection and emission nebulae: NGC 6559, IC 1274, IC 1275, IC 4684, IC 4685, Barnard 303, LDN 227, LDN 213, and planetary nebula PN M 1-41.

Trifid Nebula in HaLRGB thumbnail
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!

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.

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.

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.
