This is old data from June 2014 which I've reprocessed using v1.4a, I knew it was noisy because there were only 5 x 900s subs in total, M16 is very low for me @ 53deg N and it is at it's highest mid-June (when it doesn't really go dark!). I only managed to capture the Ha channel, clouds prevented anything else. Ah well, excuses aside... the scope was my venerable NP127is and the CCD my Atik490EX operating @ 1x1 binning, which in theory at 1.1arc-sec per pixel is way over-sampled for my usual atmospheric conditions. So much for theory, the scope still produced amazing resolution and StarTools expertly controlled the noise to produce the images below:
Full frame (almost, cropped about 50pxls per side):
and zoomed in to the centre bit which should show here at full resolution:
And yes, I tried processing this data in PixInsight too and couldn't get close to this result - which probably describes my expertise with PI more than its limitations but hey - the job was a whole lot easier in StarTools...
