Great Globular Cluster in Hercules


The Great Globular Cluster in the constellation Hercules. Isn't it magnificent? I took this shot about 4:30 a.m this morning, using a Celestron 11" Schmidt-Cassegrain as a prime-focus lens for my Nikon D3000. The constellation Hercules, at that hour, was directly overhead. ISO was set to 1600 and this was a 20 second exposure. Next up accessory is an autoguider, which will sharpen up the stars considerably. An autoguider takes 3 parts to put together, and I can't find anybody who has all 3 parts in stock. So I wait.
