Description

M31 was the first target when I got into this hobby exactly one year ago. Still remember the struggle of finding this target in the Nikon D500 live view window. The first result was just nothing - but at that time, it really made me excited for couple of days.

A year later, I decided to revisit to M31. It does mean a lot to this hobby of mine. Actually it took quite long time for me to collect the data, H-Alpha was captured in the white zone backyard. L/R/G/B was captured at TAS Atoka dark site.

It's also my first attempt to do a HaLRGB. Indeed clueless... Not sure how I made it out.

Clear Skies!
