Re: Fw: ATM Slightly off topic- Moon viewings

Ok, that makes sense...

if the scope is 37.5 inches, it's about 119 times bigger than the 
eye... so gets
about 14000 times the light.

The minimal magnification (with a 8 mm pupil) would be (37.5*2.54)/0.8 
->
119x

14000 / (119*119) ~= 1

So, at best i get the same brightness as the naked eye... 

Am I correct ?

PS: I saw you e-mail concerning off-axis guiding of alt-az scopes,
I've been burried a little bit lately, so I need to find some time to 
think
about that... but I'm going for 2 days camping in the desert in
northern Nevada... will have some time !
