Description: Extensive rework, bringing out more detail with the 36 1800 sec subs by working each channel separately, through taking non-linear, before color combining. Discovered interesting filaments extending from the top of the nebula running towards the right. I believe they are real since they appear to have structure. Anybody else seen these?
