Notes: This is a Ha-LLRGB image which shows the red H-alpha regions surrounding M31. Lots of processing on this image as integrating Ha data with LLRGB is more complicated than I thought. Just for fun, I've also included a widescreen version for those with widescreen monitors.

Great photos! Andromeda has always been my favorite galaxy since I was a kid. Just seems so perfect to me.

It's my favorite galaxy too. The next time I image it I'll do a mosaic so I can take in the whole galaxy and it's satellites.
