Re: (meteorobs) Bob Lunsford's Suggestions/Help & Nov. 19/20 Correction - LM, Marco Valois

Hi Paul Jones and all,

As far as I can understand, the LM is very effectivity. I go under its
parameters quite often. Besides, there's no way other to observe the skies,
when the its conditions seem queer or something different from the usual. I
mean: dark skies or cloudy or more blue than never, what brings certain
efforts from the observer. And, in my opinion the most interesting
phenomena: the angles and natural curves of the earth dome etc. So, this
vary on the most. Once it happens in, my case, I immediately go to the
explanation links to find any help. To the list, I politely argue once
overwhelmed of getting any difficult, if the better way is not identifying
the faint star nearby the stars with more LM to better come to its magnitude
under the parameters of Meteorobs, NAMN, IMO and so on. Excuse me, but
that's my experience. Good to read any subject related to this aspect,

Clear skies and nice Thanksgiving to all, Marco Valois
