Description

This time I used an IR-Cut filter as well as the incredible Starizona .75 reducer/coma corrector. This image is an 8.5 hour total exposure made up of many 20 second sub exposures at 300 gain. It was captured with the ZWO 224MC color camera and live stacked with Sharpcap Pro and Deep Sky Stacker. Final processing was accomplished with Photoshop CS5 and no autoguiding was used or needed in creating this image.
I hope that you like it!
