The Great Cluster in Hercules (Messier 13)
This is an image of the Hercules globular cluster I captured on May19th/20th from the Victoria Centre Observatory. The cluster contains hundreds of thousands of stars, and is about 25,000 light years from Earth. Globulars are very interesting in that they represent members of the oldest stellar populations.
This image consists of 26 minutes of 2 minute exposures with the QSI583c through a Meade 14"SCT@f10. The image was calibrated with darks, bias and flats, and stacked/processed in Pixinsight.
