Description

My first bi-color narrowband image! This nebula barely fits in the view of my EdgeHD 11" with the ZWO ASI1600 camera, so I had to crop a bit of the object out unfortunately. After collecting several hours of data, I still feel I can add more data to it... the Oxygen III (blue) is rather faint and has quite a bit of noise when stretched to make it bright.

The composition of the bi-color image is as follows:

Red Channel: HA

Green Channel: HA*0.01 + OIII*~0.01

Blue Channel: OIII
