Neither did I; however, very much there w/ my Canon T-90 and its 500 mm

Like Brian, we also had double welders glasses and students couldclearly see Venus throughout its transit. We had almost 2/3 of students
look at Venus as the transit occurred.
If Peter refers to using two (in series the ND added) may explain our (bw
& bc) failure. I think I didn't use the solar filter inaided, uuugh.
bc thougt it was the poor optical quality of his goggles.
I gave my insert from the helmet to GK for on her way the Nevada, so
couldn't double the ND.
My wife briefly projected an image onto card from cheap binoculars andtook a snap shot.
ANY phys-l message.
I mention this auspicious occasion purely to see some phys-l message -
