Artist's Description
Narrowbanding allows me to do DSO imaging from my light polluted suburban Bortle 6 backyard and even if the moon is in the sky.
Filters with a tiny bandpass of only 4,5 nm around the wavelengths of singly ionized sulfur (Sll), ionized hydrogen (H-alpha) and doubly ionized oxigen (Olll) are used with a monochrome astro camera to capture 3 different images that can be combined into a color image.
There is a catch though: SII and H-alpha are in the red spectrum, while Olll is teal. This makes it hard to produce an image with colors like the human eye would see.
The most common solution is to not even try to. That's what NASA did with the famous "Pillars of Creation" image from the Hubble Space Telescope. They assigned Sll to the red, H-alpha to the green and Olll to the blue channel. This is called the Hubble palette, a false color image that shows the distribution of the different gases.

About Ralf Rohner
As a landscape photographer and pilot I have the privilege to travel the world and visit some of the most beautiful places on our planet. I started photography as an astro-photographer, which still shows in my passion for nightscapes. While not exclusively shooting at night, a big part of my work shows the beauty of the starry night skies in combination with some iconic landscapes. Thanks for visiting my gallery.
