This image is composed of a combination of luminance data taken June 22, 2014 with my SBIG STF-8300M/TPO8RC setup, and old RGB data obtained from a Atik 314L+/ED80T-CF combination. This is the first time I image with the RC at bin 1x1, and I had some focusing and sensor condensation issues, which I expect to fix in the next couple of days.

I am still deciding if it's worth to image at bin 1x1 due to poor seeing conditions at my imaging site, or continue binning 2x2 to obtain a not so different result in terms of image clarity. Still investigating.
