The Great Hercules Globular Cluster, M13, NGC6205

After seeing Ollie's Astro and Russell's Astrophotography recent videos of their M13 captures, I thought I would head over there myself and have a go at it. I've never looked at a cluster, let alone try to image one.

This cluster is approx 145 light years in diameter, comprises several thousand stars and is around 22,000 light years away.

This was captured with the Edge HD 11", 0.7x focal reducer and ASI 2600MC-P colour camera.

Below are the two videos from other astrophotographers who also captured the cluster recently.

Russell's video:

Ollie's video:

Within the image, there is also galaxy that can be seen to the middle left of the cluster, this is IC 4617 and is located approx 498 million light years away.

The image was stacked from 39x 120s exposures for a total integration time of 1hr 18 minutes. The camera was set at -5'C and had a gain of 121.

I upload my images to Telescopius, and you can find my profile at:
