The Eye of god - 26 Oct - 26 Nov 2019


The Helix Nebula (NGC7293), AKA "The Eye of god" in narrowband color.

Exposed for multiple nights during October and November 2019 through HII, OIII narrowband filters using a full spectrum modded and cooled DSLR through a 8" SCT at 2032mm focal length.

Because a OSC sensor was used to expose this image, I was able to extract Hbeta from the HAlpha and OIII subs (in their corresponding blue channel) and stack them to be used as a real Blue channel in the final image.

The green component from OIII is the green channel and red component in HAlpha is the red in RGB color mapping. Because of the use of a OSC camera, I did not have to generate a synthetic channel as is usually done with bi-color narrowband images.
