A bit tougher to image/process than first thought. Dim object and after seeing the first sub, I should have upped the exposure time. Although there was over 5 hours of time, 2' subs was not enough to bring out the fainter detail. Over-stretched to bring out more detail.
Moon was at 100% also but not near the subject.
