Description

Little bit of a labor of love.

Really wanted to go very deep with narrowband filters on Andromeda to see all the nebulae, supernova remnants, and other gases.

This is a Red Channel enhanced with Hydrogen data, Green Channel enhanced with SII data, and Blue Channel enhanced with OIII data composite.

During processing I found a figure 8 in the OIII data and took a lot of effort but narrowed it down to a supernova remnant, SNR BW-59.  You can just see it in the DSS B band and GALEX.  It is at the coordinates (00 44 18.6, +41 18 53).  I started a discussion of it on CloudyNights https://www.cloudynights.com/topic/887589-oiii-figure-8-in-andromeda-galaxy/#entry12878965

I really love all the different nebula region throughout though.  Some remind me of objects in our own Milky Way.

I did an annotated version highlighting all the globular clusters and supernova remnants.  It is definitely worth browsing the full resolution image of the annotated version!

I  also annotated all the Globular Clusters and Supernova Remnants, be sure to zoom in on this one!!

Lastly I did a composite showing all the different channels
