this is M13, The Great Globular Cluster in Hercules
Imaged with the Moravian G2-8300 at my 12″ f/4 Newtonian with L:R:G:B=230:80:80:80 minutes. Subexposures were 10 minutes for luminance and 10 minutes for RGB and L:R:G:B=214:120:120:120 minutes. Subexposures were 2 minutes for luminance and 2 minutes for RGB.
So the total number of frames in this image is 335. So I processed 5.3 GB of data with CCDStack, PixInsight, NAFE and Photoshop for this image.
