Hercules Globular Cluster (M13) - a photo on Flickriver

Hercules Globular Cluster (M13)

I took this image with my William Optics FLT132 apo refractor, with the FLAT68III flattener at 910mm focal length and f6.9.
I used the ZWO ASI2600MC Pro and Antlia Triband RGB Ultra filter. AM5 mount and ZWO ASIAir plus. Overall integration time 2h30m with 30s, 60s and 120s subs.

Pre and post processed in PixInsight and Affinity Photo 2.

Thanks for looking and clear skies!

Information on M13:
-------------------------------------------------
"The English astronomer Edmond Halley discovered M13 in 1714. When Charles Messier added M13 to his catalog in 1764, he was convinced that the nebulous object did not contain any stars at all. Because they are so densely packed together, the cluster’s individual stars were not resolved until 1779. Near the core of this cluster, the density of the stellar population is about a hundred times greater than the density in the neighborhood of our sun. These stars are so crowded that they can, at times, run into each other and even form a new star. The resulting “blue stragglers” appear to be younger than the other stars in their immediate vicinity and are of great scientific interest to astronomers.

M13 contains around 100,000 stars and it's located 25,000 light-years from Earth with an apparent magnitude of 5.8."
