[Lvas] JBoronVirgo Diamond

Tue Apr 7 20:22:10 PDT 2009

Very nice Roger. I tried to view the Virgo diamond Sunday evening but the 
light polution was too bad. I think we had dust haze which added to the poor 
visibility.

I have the manual circles on my G-11 and I,like it a lot. I have thought 
many times of adding the Losmandy Gemini system but cannot justify the cost 
in my mind.
