Description

Being the brightest non-solar system DSO in the sky, needed 500 MaskedStretch steps in PI to bring out much dimmer spiral arm regions.

Note: with Halpha version, used lower resolution Ha (approx 3X3) from ZWO ASI 1600MM and ZWO 7 nm Ha filter taken two years earlier.

Title: M31 With Halpha

Description: Adding Halpha using technique: https://www.highpointscientific.com/astronomy-hub/post/astro-photography-guides/ha-rgb-pixinsight. Highlights the difficulty of minimizing coloring central glow and maintaining Ha spiral arm regions, due to very large dynamic range of M31.
