When stars like the Sun are near end of life, they send their outer layers into space to create glowing clouds of gas, a planetary nebulae. This ejection of mass is uneven, and planetary nebulae can have complex shapes. This dying star is moving rapidly through space, resulting in a long tail of ionized hydrogen gas.

Little Gem Nebula NGC6818 thumbnail

Perhaps too small of an object for amateur equipment to tease out any details, I decided to try my luck on the Little Gem Nebula. NGC 6818 is roughly 6000 light-years away from Earth. The glow of the cloud is just over half a light-year across.

Planetary Nebula IC5148 thumbnail

A glowing shell of ionized gas ejected from a dying star, IC5148 is at the end of its life, shedding its outer layers and contracting from a red giant to a white dwarf.

Shapley 1 Planetary Nebula thumbnail

Shapley 1 is a planetary nebula in the southern sky with a magnitude 14 white dwarf at it's center. It is approximately 4900 light years away, and one third of a light year across.

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.

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.

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).

Astronomy as Art - The Many Faces of Narrowband thumbnail

Narrowband images are rarely presented as true color light. When imaging in narrowband, colors are assigned to each channel based on the specific emission lines captured. One of the most common choices is the SHO Hubble Pallet, but the choices for mixing colors are endless. Here are 9 examples of how an image of a planetary nebula may be colored.

First Narrowband, Difficult Subject: Planetary Nebula Sh2-313 thumbnail
10-May-2016
For my first foray into narrowband imaging, I have chosen a very dim & difficult target: planetary nebula Sh2-313, also known as Abell 35 and PK 303+40.1
