Hi Dean,
Isn't it so awesome to see something that far away!!!! I had dreams (really I did
) for months of finding this one as I could never get it from my back yard and a few weeks ago I was at a dark site and "bam", got it with only a 6" dob. I couldn't see any details though, despite looking through a 10mm Pentax xw, but was awesome nevertheless.
My hands were too frozen and I could barely feel my fingers, to throw a barlow on, but I don't think I would have gotten much more as it was fairly dim to begin with. It was good to read the detail of it that you got through your 10", because I will be the proud owner of one that size hopefully this weekend!
So lookout M-104, I'll be hunting you down again
I now own gloves by the way, apparentally that are reaaaaally necessary.

Regarding the light from your neighbours house getting in your way, I have read that people cover their whole head with something when looking through the eyepiece? Maybe someone can comment on that and clarify it.
