Mr. David DeVorkin, Senior Curator
Division of Space History
Public
Observatory
Mr. David DeVorkin, Senior Curator for the Division of Space History, National Air
and Space Museum, Smithsonian Institution, describes
a recent observing session with visitors to the museum's public observatory:
..."Even with the heat these days the crowds continue -- July 3 and 4 we served about 1000 visitors
in 8 hours."
..."When we observe planets like Venus and Mercury during the day, we use the DFM Articulated
Relay Eyepiece - it is a wonder!"
..."We've stopped observing the Sun with the 16-inch telescope though -- too much magnification.
The sky issues just do not allow for it. We observe the sun with an attached Lunt H-alpha telescope and
the 4-inch finder fitted with a projection device called a 'Sun Gun'."
..."If we get better seeing in the fall, we'll go back to the 16-inch telescope, observe the total
Sun with the 'Sun Gun' and details (if they ever come back) with the DFM Articulated Relay Eyepiece."
..."Visitors really seem to like to view the Sun in different ways to gain better comprehension
of what they are seeing." |
