      Description

      Imaged over the last two months from Marathon Texas. The fourth image out of my system to highlight the sheer light gathering capabilities of a Takahashi FSQ106 system coupled with a 645 reducer and a QHY600 camera. I'm amazed at the ease and beauty each time I use it. Captured during the new moons of June and July, the image is comprised of 8 hours of L-R-G-B data with 1 minute subs and 120 frames per channel.
