I have recently been doing my shopping for image processing software, "thanks" to super cloudy and rainy nights (and an impromptu thunderstorm that came in amazingly quickly one night that appeared to be clear). Up to now I have looked at free solutions (Gimp 2.9 with 16 bits processing, Fitswork, DSS), Startools, Pixinsight.
While I was a big big fan of Startools very quickly, I recently looked at just the newbie tutorials from Harry for PixInsight, and got the attached picture for the Eagle Nebula (very difficult to process image with loads of noise and no dithering).
Compared to my earlier Startools attempts this is much better. http://www.cloudynig...5921787/page...
Maybe it is my IT background, but Pixinsight seems like an amazing tool for the moment, and I guess I will need to give them my money by the time my trial expires!
