M13: What a Difference 10 Months Makes

About 10 months ago, I started getting into Astrophotography, which has been an amazing and positive experience for me so far.  I started taking photos of Deep Sky Objects (DSO’s) with my Nikon D7000 DSLR and I was quickly enthralled with the beauty of what existed out in deep space.  One of the first DSO I imaged with my DSLR was M13, the Great Globlar Cluster in Hercules.  I remember being in awe that the pitch black patch of sky I pointed my telescopic contained so much beauty.  After learning how to do some rudimentary unguided imaging with my DSLR, I wanted to see if I could get more detailed photos so I looked into purchasing a CCD camera, which is a specialized imaging system for Astrophotography.  I received a ton of helpful advice from Michael Caligiuri who has been a tremendous source of inspiration and knowledge.  I also did some research and subsequently purchased a monochrome SBIG ST-2000XM and a filter wheel from Astromart so I could now image DSO’s across the Luminance, Red, Green, and Blue channels.  Flash forward to present day and here is a comparison of M13 taken 10 months and one I recently took back on June 4th:
