Planetary Nebula NGC4361 thumbnail
NGC4361 is a planetary nebula with spiral arms similar to a galaxy. The star at the center of the nebula is shedding its outer layers while contracting to form a white dwarf.

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.

Robins Egg Nebula thumbnail
NGC 1360 is known as the Robin's Egg Nebula, primarily due to its blue hue from strong oxygen-III emissions. It is a diffuse planetary nebula 1794 light years away. Presented is a narrowband image with H-alpha emissions mapped to red, and OIII emissions mapped to both green and blue (HOO palette).

Symbiotic Star System R Aquarii thumbnail
R Aquarii is a symbiotic star system where a white dwarf is drawing material from its binary red giant companion. The extra material is then ejected into space in loops and jets.

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.

NGC 2736 - The Pencil Nebula thumbnail
NGC 2736, known as the Pencil Nebula is a part of the supernova remnants from the Vela pulsar, 815 light years away.

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.

Narrowband Helix Nebula thumbnail
I've already done the Helix Nebula in natural colour, so I've imaged it again in narrowband. Lots of H-alpha and Oxygen-III, but barely any Sulfur-II.

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.
