Globular cluster Messier 13
Up till now I wasn't able to make a decent picture of a globular cluster. Last night I amed the telescope at The Great Globular Cluster in Hercules. This picture consists of 50 frames. The exposure time is 30 seconds at 1600 ISO. I stacked the frames with DeepSkyStacker and touched it up a little with Photoshop.
