Do you observe south of the Equator?  Are you looking for a significant observing challenge?  Then the Bambury 600 Southern Skies Observing Certification is for you.  The Astronomical League and OZSKY are offering a joint certificate to those who complete the entire list of 600 observations.  You do NOT need to be an AL member to participate.  This Observing Certificate allows for Imaging and Remote Telescopes.  Information and rules can be found on the Southern Sky Telescope Observing Program web page:
