M 13 / NGC6205 Globular Cluster in Hercules

M 13 / NGC6205 is the Great Globular Cluster in the constellation of Hercules. It is one of the largest and most beautiful globular clusters visible from the northern hemisphere.

At magnitude 5.8, M13 is visible to the keen unaided eye at a dark-sky observing site. It is located about 25,000 light years away. It has an apparent angular diameter of 15 to 25 arc minutes, depending on the size of the telescope used to observe it. This corresponds to a real size of about 145 light years. It contains hundreds of thousands of stars.

M 13 was discovered in 1714 by Edmond Halley and catalogued by Charles Messier in 1764.

Galaxy NGC 6207 can be seen just below center toward the lower left. Another small faint galaxy, IC 4617, can also be seen to the left of center of the photograph.

HD 150998 is an orange giant star in the constellation Hercules. At 1,350 light years away, it shines at an apparent visual magnitude of 6.86.

HD 150679 is a white main-sequence star in the constellation Hercules. At 371 light years away, it shines at an apparent visual magnitude of 7.29.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
