Astrophotography Globular Cluster

Astrophoto: Great Hercules Cluster – Messier 13 – 06/23

Clearly rounder and less inflated stars. The development of the new material from last summer has paid off.

My 2023 photo of the 22.000 LJ away Great Hercules Cluster M13 in the constellation Hercules.

31 Subs each 180s with my Vixen VC200L VISAC at 1800mm focal length on my HEQ5pro with my CANON EOS M100(a) in Koblenz, Germany.
Stacking and integration was done with PixInsight.
