The Eye of god

[MarsG76]

Hello All,

Sharing with you my latest image, The Helix Nebula (NGC7293), AKA "The Eye of god" in narrowband bi-color.

Exposed for multiple nights during October and November 2019 through HII, OIII narrowband filters using my full spectrum modded and cooled Canon 40D DSLR through my 8" Celestron SCT at 2032mm focal length, tracked with a CGEM mount.

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.

Clear Skies,

MG

Whatever you did with those channels it has certainly worked MG.  A cracking Helix!

Thats a very nice Helix MG.

This is way too far south for me to see, let alone, image.

Thanks for sharing.
