Re: (meteorobs) Re: LM's and the Milky Way




lunsford>>George it is obvious that you must have a perception approximately
0.8
magnitudes lower than Marco and I. If I see a 6.0 sky you will rate it
5.2. If I see a 6.8 sky you will rate it as 6.0. It is not that you are
seeing the Milky Way under a brighter sky but rather that you rate the
LM as being lower. The sky brightness will be the same for the both of
us.

In summation, I believe that when George and I get together we see the
same sky brightness, the same Milky Way, but the estimated LM's will be
0.8 magnitudes apart due to different perception factors.<<

This seems to make more sense to me than anything else I've came across about
it. The hurdle that I had to jump over was the concept that the sky brightness
and the Milky Way would appear the same to us. It's just that I'm unable to
see dimmer stars not much beyond 6.0.  Once I have a dark sky and reach a 6.0
LM, I seldom see very much of a change for the rest of the night unless
something more overwhelming occurs...namely dawn, moonrise or a cloud that
bounces ground light into the sky from the local Indian Casino.
