That is interesting. I was able to pick it up with averted vision tonight, but 
that was a disappointment compared to yesterday. And the fact that you were 
able to pick it up tonight from town is a little weird. I wonder if I had more 
horizon light to contend with since I didn't have the Tucson mountains blocking 
some of the horizon glow? I know my vision was fairly good because I was able 
to pick up Jupiter naked eye while the person I was photographing with had to 
use bino's. Doesn't mean much because he could have just been blind as a bat. I 
am hoping tomorrow is even better with the Moon. BTW, I was out on McCain Loop 
just west of the Desert Museum. I might do that again tomorrow or head a little 
further to Saguaro West near Golden Gate Rd and Sandario.
