IC4603 and IC4604 Showing Rho Ophiuchi Color Transition thumbnail
27-Apr-2017
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.

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.

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.
