Re: (meteorobs) Eclipse fron NJAA observatory
Actually, besides the rather frivilous nature of this, Bob's response
brought to the fore a different way of approaching limiting magnitude...not
the one that I was *looking* at.
Limiting magnitude is really made up of two
elements...Transparancy-from which I derived my estimates, and dark sky
illumination- what Bob referred to. Now I have to let that simmer in my
brain for a while....where it will probably do real damage.
By the way, we did have about 5 people last night asking if they could
look at the eclipse thru the 26"er..dot despite the fact that it was so cloudy
if the sun was in the moon's orbit you still couldn't have seen it.
Always fun to educate the masses :-)

No wonder you did not see any meteors! With a limiting magnitude of -30
you would need a pair of dark shaded sunglasses to protect yourself from
the intense glare.
