Hi Sirko!
Thanks very much for your explanation on Noctilucent Clouds!
I was just trying to find out how to say this in plain English...
While Marco observed the NLC from Voorschoten very near the beach of the
North-sea I photographed the event from de Bilt which is about 70
kilometers to the east in the center of the Netherlands.
I used a Canon T-70 equipped with a 3.5/35-105 objective and command-back.
I used the Fujichrome Sensia 100 film and started photographing at about
21:15 UT and stopped at 21:55 UT. Exposuretimes ranged from 5 to 15
seconds. The NLC were at their finest around 21:20 UT when they reached to
20 degrees altitude. They were wonderfull in a 9*63 bino.
Casper.
Leonids-'98? A once (twice?) in your lifetime appearance! You can't afford
to miss it!
