M31 | The Andromeda Galaxy in LRGB + H-Alpha

Details

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!

[Detailed images]
-The first image shows the complete composition of all LRGB + H-alpha channels.

-The second image shows only the processed LRGB image without the added H-alpha signal.

-In the last image you can only see the pure H-alpha signal from the galaxy itself and the nebulae from the Milky Way "floating" in front of M31.

I spent over 4 hours just editing to achieve this result and I am very pleased.
