Lew et al,

No, Lew, haven't had the pleasure yet!

Ah, come on! Surely not that far out! For our West Virginia observing on
the Friday evening, I know I saw a number of meteors quite a distance from
my center of field, but I don't recall any <quite> that far out.... ;>
Haven't decoded that tape yet... guess I should do that!

Have never heard the umbrella idea... but not a bad one! I have heard of
people putting occulting bars in eyepieces so as to dim the glare of bright
stars, in order to pick out faint galaxies... same principle! Occulting
bars, disks, etc...

True, Lew! However, I'd give serious consideration <any day> to any advice
I could get from George! ;> He has been extremely helpful over the past
couple years with advice, and helping me getting back into serious observing
after a number of years of not being involved in it.

I'll ditto that....

One definate reason to put up some kind of obstruction of the moon is to avoid
an involuntary viewing of its glare while watching for the meteors. You can't
help wanting to look at it, if for no other reason than to get an idea as to
how long you've been out, the time.
