You might be able to work with that Orion stack. Is that a stacked image or a single sub? At least your getting something out of short subs. What ISO was that? The higher the ISO you use the more skyglow your going to collect for any give sub. Short subs at ISO 400 might over come the glow better. You will still have CA to deal with but Orion is bright enough to over come skyglow in short subs, i think.
