M13 - NGC 6205 Great Globular Cluster in Hercules

M13 - NGC 6205 Great Globular Cluster in Hercules

This was my third attempt at at M13 and I think my best yet. I increased the ISO to 6400. I took more lights and darks. Still need to work the bias and flats into the process to improve my image even more. I didn't push the saturation as much during the processing so the blues and yellows are quite as apparent as other peoples images.
