M31 | The Andromeda Galaxy in LRGB + H-Alpha
This is my best shot of the Andromeda Galaxy so far! It is also my first image from my new QHY268m and I am simply overwhelmed!
-The first image shows the complete composition of all channels LRGB + H-Alpha.
-The second image shows only the processed LRGB image without the added H-alpha signal.
-The last image shows only the pure H-alpha signal from the galaxy itself and the nebulae from the Milky Way "hovering" in front of M31.
I spent over 4 hours just editing to get this result and I am very pleased.
