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.
My 1st attempt through my own telescope. It's very tricky ... align...put camera on...focus...realign..knock mount..swear a bit..refocus....battery runs out...replace battery.....refocus....knock mount again....refocus...take pictures....
Hope you like it !
First go at long exposure astrophotography at prime focus with a modified Philips SPC880NC (flashed to SPC900NC) webcam.
5 second exposures because my scope wasn't aligned properly. Perhaps half a dozen frames stacked with Registax, then manipulated in GIMP.
Telescope is a SkyWatcher Explorer 130PM f/5 Newtonian.

WIKI: Messier 13 (M13, NGC 6205), also called the 'Great globular cluster in Hercules', is one of the most prominent and best known globulars of the Northern celestial hemisphere.
It was discovered by Edmond Halley in 1714, who noted that 'it shows itself to the naked eye when the sky is serene and the Moon absent.' According to Charles Messier, who cataloged it on June 1, 1764, it is also reported in John Bevis' "English" Celestial Atlas.
At its distance of 25,100 light years, its angular diameter of 20' corresponds to a linear 145 light years - visually, it is perhaps 13' large. It contains several 100,000 stars; Timothy Ferris in his book Galaxies even says "more than a million". Towards its center, stars are about 500 times more concentrated
