Very cool target, Mike; I don't recall seeing this one before.
I'd like to say that you've done an amazing job... but... I have no basis for comparison
Seriously though, I had a quick poke around and there's not many images of this. I found one, apparently captured with a 32in RC (RCOS) in the Mount Lemmon observatory and yours compares very favourably.
Edit: ha, I guess it pays to read the comments as well as the original post ;-)
