Sharpless 63 thumbnail
Although categorised as a hydrogen emission nebula, Sh2-63 lacks the bright red colouring typical of similar objects.

Red Spider Nebula thumbnail
The Red Spider Nebula (also catalogued as NGC 6537) is a planetary nebula located near the heart of the Milky Way.

The Butterfly Cluster thumbnail
The Butterfly Cluster, Messier 6, is an open cluster of hot blue stars with the brightest member being an orange giant star. Behind the cluster is the orange light of the Milky Way, and a beautiful cloud of excited Hydrogen alpha gas.

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

Prawn Nebula in Emission Line Color thumbnail
IC 4628, sometimes known as The Prawn Nebula, is an emission nebula located around 6000 light-years away in the constellation Scorpius

Prawn Nebula in Natural Color thumbnail
IC 4628, sometimes known as The Prawn Nebula, is an emission nebula located around 6000 light-years away in the constellation Scorpius

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.

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.

Saturn Nebula 2017 thumbnail
After a brief hiatus from astronomy to build a new, larger observatory, I've chosen another difficult target that was surprisingly bright.

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.

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.

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!

Cosmic Bubble NGC 6781 thumbnail
Stars such as our Sun do not contain enough mass to finish their lives in the glorious explosions known as supernovae. However, they are still able to salute their imminent demise into dense, Earth-sized embers called white dwarfs by first expelling colourful shells of gas known as planetary nebulae.

Saturn Nebula thumbnail
The Saturn Nebula is a tiny but complex planetary nebula, ~4000 light years away in Aquarius. The Saturn Nebula gets its name from its resemblance to the planet Saturn to the observer.
