Thanks Barry.
Brother in Law & I went out to our normal "dark" sky sight. I couldn't see it,
albeit I did enjoy taking the time to observe m66 more closely than what I have before.
I could see some of the spiral structure and a bit of the central region as a semi circle. I found the view through a 9mm EP the best combination of dark background and at 183x, magnification.
Alas in between the clouds, people driving into the lookout and the encroaching LP of Ipswich I couldn't see it. The BiL cought a glimpse of something at about the 10 o'clock position relative to the core as viewed in a reflector, i.e. Opposite the row of three foreground stars. So the right general area. But that could also be one of the bright star forming HII regions... Who knows ?
As disappointed as I was with the whole outing last night, observing is still better than not observing
