Description

There are some >4,000 images of M13 on AstroBin and here is my latest to add to the collection! A few nights of clear skies are promised here so I thought I would start with M13 and hopefully improve on my image from 2015 with the benefit of using PI. I took the luminance for this on May 26th which was a night of very good seeing, RGB on 15th/16th July. Using 60s subs for LRGB to minimise loss of core detail. More integration time needed to reduce background noise but the summer nights are short! Comparing my previous attempt this image is better in terms of background gradient, star alignment, core detail and resolution so I'm happy with that :-)
