Description

Westerhout 5 is a large nebula that can be found 7,500 light-years away in Cassiopeia. It is rich in Hydrogen Alpha and is often photographed with its neighbor, the Heart Nebula.

This image was captured from our Bortle 9 backyard in Las Vegas. We of course had no choice but to use narrowband filters to combat the extreme light pollution.
The Soul Nebula is a great target for bi-color combination, but we decided to use all three filters anyway and so imaged it in Hydrogen Alpha, Sulfur II, and Oxygen III.
We are very pleased with the end result, especially because most of the HA was taken during an almost-full moon so we were a bit afraid to get gradients or vignetting from it.
