[Lvas] Losmandy G-11

Wed Apr 8 04:51:46 PDT 2009

John,

I'm sorry that I said GM-11. I am certainly familiar with your Losmandy G-11 mount. 

I was never so happy as when I lived in a very light polluted neighborhood back in the 70's and learned how to use my manual circles on my ES 4-1/4 inch reflector. I thought that I had conquered the world. I would observe within 100 foot of the brightest street light that you have ever seen.

I could still see some of the brighter messier objects. Star hopping was almost impossible.
