Hi Don,
M51.
Andrew, John and I looked at it through Larry Mitchell's 36" at the Texas
Star Party last May.
That specific view of it through that much aperture is the closest I
have seen a galaxy resemble visually what it looks like photographically.
In fact if you were an astrophotographer and saw the same view, I think you
would just put the camera back in the carry case and say, "why bother".

You can just look at it in real-time!
I believe Andrew may have looked at it before with the same scope,
but we were positively stunned. You just don't get that sort of view of it from
here and that much aperture seems to provide enough photons for the receptors
in the eye to work effortlessly.
So apart from the specific object and the latitude you observe it from, aperture
and seeing can make all of the difference.
Look forward to seeing you again soon and getting some more WOW's going.
Best regards
