This image was captured using Ha and SII filters. Each filter was used to capture seven 20 minute exposures giving a total integration time of 4.67 hours (280 minutes). Originally, seven 20 minute OII images were captured as well. However, due to a very slight tilt in the filter wheel, internal reflections ruined the OIII set of images.
