A tiny Zoo Gem which turned out to be an incredibly dramatic galaxy. Unfortunately it's still very small even when Hubble views it, and the best color imagery I know of is from SDSS DR9, so I took some artistic license to it and colored it how I think it might be, based on my experience from looking at these things. Make no mistake—the color here, though based on the SDSS imagery, is almost certainly not correct. It should be within the ballpark, though.
I removed a few cosmic rays, and while doing so, I thought man, there are a lot of faint field stars in the foreground, like a nearby galaxy is in front of it. Took a look at the sky map and sure enough it's behind the halo of Andromeda, so most of those faint foreground stars are Andromedan.
Data from the following proposal were used to create this image:
