M13 star cluster. 30 second photo done with a Canon Rebel 350D Camera, Nexstar 8SE telescope with a 25MM eyepiece and a 0.5X focal reducer that reduces the Nexstar from a F10 down to an F5. Im pretty new to this stuff and my home made timer switch took a crap so I had to use the cameras internal timer which is max time of 30 seconds. I guess it didnt turn out too bad.M13 is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable star V11 with an apparent magnitude of 11.95. M13 is 25,100 light-years away from Earth.The Arecibo message of 1974, designed to communicate the existence of human life to hypothetical extraterrestrials, was transmitted toward M13. The reason was that with a higher star density, the chances of a life harboring planet with intelligent life forms, were higher. Even though the message was transmitted, M13 will no longer be in that location when it arrives. The sending of the message was more of a technological demonstration, rather than an actual attempt to contact life. (wickepedia)

This is the Hercules Cluster, a.k.a. Messier 13, a globular cluster of 100,000 stars that lies 25,000 light years from us. It was discovered by Edmund Halley in 1714.
Taken from my driveway over three nights using a Sky-Watcher 600mm 80ED, a ZWO ASI178MM-Cool camera, and ZWO red, green, and blue filters, on a Celestron AVX mount. Aligned and stacked in DSS and processed in Photoshop. 2 hours of each color for a total of 6 hours.
A group of Wheaton Academy students put together a detailed diorama of the allied landings in France on D-Day.
Cantigny Park in Wheaton commemorated the 70th anniversary of the D-Day landings with vehicles, reenactors and a series of engaging activities so that young people could learn the history in engaging ways. As a special treat, there were veterans of the beach landings who were there to share their experiences and answer questions.
