Noisey helix

This was taken using a SW120 ED refractor and celestron nightscape . 16 x 5min exposures, 2x2 binning( about 2.6Mp res) stacked and some processing in astrofx then final processing in PS. had to filter out some of the noise . I think I will have to up the exposure and get more subs to get a better picture. I think this subject needs more aperture at about this focal length to gather more light in a shorter time. Maybe a fast newt might be the next purchase?
