ObSIG (Observing Special Interest Group)
CLICK IMAGE TO DOWNLOAD PDF These programs are for beginners, to help everyone familiarize themselves with the night sky. The rules are simple, just observe the 20 required objects from the lists provided. To get the 20 objects, you will need to observe and record any ten deep sky objects, then observe and record any ten double stars. That’s it. That is a total of twenty objects observed using a telescope. When recording your observations, you need only log the date and time observed. At the completion of the program you will receive recognition from CLASS and a nice lapel pin to wear proudly. There is no time limit in completing the program, and you may observe the objects from either the city or the country. Any size telescope may be
used. All objects are listed in Right Ascension order so that you will know
if they
are observable at the time of year that you attempt this program. Right Ascension
is in hours and minutes, while Declination is in degrees and minutes. Types
of objects are open clusters, globular clusters, and planetaries. Finally,
size
is in minutes with planetaries in seconds. Double star separations are in seconds
as well. When sending in your log sheets, please include your name and address. We
will then send you your CLASS Telescope Observing Program lapel pin. To help
in recognizing the twenty objects, you may want to check out a book at your
local library or you can purchase a planisphere or a simple sky map online
at www.skyandtelescope.com. And if you need a little help you can ask questions
at the next ObSIG meeting. Good luck, clear skies, and good observing. These
