Amazing tool!

This program is excellent! It is easy to use and makes stacking, aligning, and blending multiple star shots a breeze. The result is far less noise and pinpoint stars if you take short exposures of the sky. I use a Nikon D800E and if I take 10 exposures each at ISO 6400, f/2.8, 14mm, for 10 seconds each, the result is pinpoint stars and much lower noise then I would have seen with a single ISO 3200 exposure of 25 or 30 seconds. This program respects your input images’ color space and bit depth, so you can import 16-bit TIFFs in the ProPhoto RGB color space and the result will be a 16-bit TIFF in ProPhoto RGB.
