Description

This is my first attempt adding Ha data to LRGB data. The Ha really emphasizes the star forming regions of the Andromeda galaxy.

One thing I did not expect is what looks like blue open star clusters in the outer arms of the galaxy (blue patches of stars in the upper right). M31 is always a fascinating target.

I felt my original image was overly blue in cast. So, I adjusted the color calibration using the PixInsight Photometric Color Calibration process to create this version.
