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.

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
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
