62 ASTRONOMY • SEPTEMBER 2017


As amateur astronomers know,
high winds tend to ruin the seeing,
the measure of atmospheric steadi-
ness necessary for observers to dis-
cern small details in celestial
objects. And wind is doubly trou-
bling in the desert Southwest
because it kicks up profuse amounts
of dust. Too much dust over pro-
longed periods will coat optics, but
the more immediate concern is its
insidious penetration of the
mechanical parts of telescopes —
focusers, mounts, and drives. Oh
well, nothing to do but wait and see
what the next 12 hours would bring.

Chatting up
astronomy
Of course, a lot happened in that
half-day between breakfast and

evening twilight. After a lunch
whose quality far surpassed other
star parties I’d attended, Dave and I
each gave two talks. His first one
was “The New Cosmos: Great
Discoveries of the Past Decade,” an
up-to-date look at the state of
astronomy. People asked lots of
thoughtful questions, and I think
Dave could have gone another hour
if time had allowed.
After a short break, I was up
next, and presented “The Great
American Eclipse of 2017,” my main
focus during the past three years.
My goal during that talk was to light
a fire under anyone with an interest
in astronomy who was thinking of
skipping the eclipse.
A longer break followed, then
Dave wowed everyone with

“25 Exotic Targets for Deep-Sky
Observers.” Examples included the
weird galaxies NGC 520, Centaurus
A, and Maffei 1, and odd nebulae
like the Witch Head Nebula and
Hubble’s Variable Nebula. His
knowledge of objects outside the
boundaries of our solar system is
impressive indeed. Finally, I gave an
overview of the objects that would
be up when night fell with “What
We’ll See Tonight.”

Nightfall
After my second talk, we adjourned
for a two-hour break. Our caravan
then gathered in the hotel lobby
and drove from Lordsburg to the
DSNM site in Animas. The half-
hour drive was quite scenic.
Plus, the percentage of cloud cover
continued to diminish with each
passing mile.
Upon arrival, we were all wel-
comed into the DSNM Ranch
House for a chuck wagon-style din-
ner. There was plenty of food for
everyone, including a chips-and-
salsa appetizer, a wide variety of side
dishes, and even sweets for dessert.
Roughly every two minutes, the
door would open, and someone
would venture out to take a quick
look at the sky and assess the wind.
“Sk y ’s clea r ; w i nd ’s st i l l up,” wa s t he
report heard the most. As the Sun
