Join the TVS Messier Marathon observing party


by Dave Sworin


   As you already know, both club Messier Marathon observing party dates were rained out. Fear not, this does not dampen our enthusiasm for independent Messier observation. Full rules for the event are reprinted in this issue, and  you have  plenty of opportunities to try the Messier Marathon challenge any time from now through May 30, 1999. 

   Just follow the rules printed below, record the data required, and postmark your entry by May 31, 1999.  This gives you plenty of chances to do your best.  Prizes and certificates will be awarded. The board of directors has empowered Alane Alchorn (circlewing@aol.com) to select a variety of desirable toys and trinkets for the winners. You will find more details on the prizes and certificates in  future editions of
Prime Focus.  If you have questions about these rules, e-mail Dave Sworin (Davesw5@aol.com).  We're keeping this challenge informal and trying to give everyone an even chance, so join in the fun!

In the case of a visual observation, this means that another person must look in the eyepiece and see the object.  In the case of a CCD observation, the witness may review the picture of the object immediately on a computer screen.
