Description

I finally received the data for Messier 13. The posting I made earlier this week was of the luminance version of this, and consisted of fifty nine 30 sec exposures and thirty 300 sec exposures merged, using HDR combination in PixInsight to protect the core from over saturation. In addition I have now added 12 of each in RGB, each at 300s long each. I am very pleased that I have kept the 'propeller' after the further processing, and closer inspection shows that I have also got other propeller-like structures coming through too. I have never really seen the internal structures of M13 before.

This was taken through the ITU scope in Southern Spain in Fregenal de la Sierra.
