The Astronomical League is working closely with the NASA Hubble Telescope Team on future collaborative efforts (Observing Challenges, etc.).  As opportunities become available we will announce them here.  We hope you will take advantage of these Challenges.  Our first step in this process is to include links to the Hubble Telescope collections of Messier and Caldwell Objects.  Links to these collections are now at the bottom (in the Links section) on the web pages for the Messier Observing Program, the Binocular Messier Observing Program, and the Caldwell Observing Program.  Enjoy!
