Description

After weeks of cloudy wet weather here in southern Spain, I managed to capture 2.5 hours of imaging with a full Moon and 100% humidity! 

This was a challenging image for me to make something reasonable with, especially with my Lum flats being almost useless.  It looked like the filter did not centre correctly in the frame creating 3D donuts.

I think I am pushing the data to the limit but really enjoyed seeing what could be done with PixInsight tools.  The best tool for star cluster stretching I have found to be GHS.  It has fine control over the globular core without blowing out the outer star field. 

Thanks for looking.
