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 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!
