M13, OSC, Bortle 8

[Lee_P]

My first globular for a while! Makes a nice change of pace from faint nebulae and galaxies. As ever, this was taken from Bristol city centre. I'm happy with how my Askar 130PHQ performed, producing good stars that could be easily tweaked during processing. I tried to keep the core glowing but not overblown.

More details, including a comparison with Askar FRA400 data, can be found on my website: https://urbanastrophotography.com/index.php/2023/07/17/hercules-globular-cluster-m13/
