Well, I have revisited the Sombrero Galaxy. I was getting some good seeing that night and guiding was well behaved so I thought I would give this object a try. I did the luminance on a 2x2 bin in an attempt to get some strong signal - I think this was a good move. I also took a few 1x1 bin. The ole C8 can still catch a few photons.
