Re: AO 51 dimensions


My original comments on this issue were that I am not out to persuade. I 
just thought I would share some information that I have acquired from my 
study of astronomy. I enjoy stargazing a lot. The smallest object the human 
eye can detect (according to the astronomers who have written on the 
subject) is a magnitude of +6. The sun is a -27 ( astronomers use a 
counterintuitive scale). Someone here on the BB stated that AO51 is a +9 
(three levels below naked eye seeing). That would be like being down 3 S 
units. You might be able to see  magnitude +9 from a "dark sky" location 
with a pair of binoculars or a small telescope.

I believe in letting everyone draw their own conclusions. I never told my 
two kids that there was no Santa Claus, Tooth Fairy or Easter Bunny. They 
just came to that on their own.

>>AO 51 is approximately 9 inches wide by 9 inches long and 9 inches deep.
