Thank you, William. With this camera I am not using Darks. Set it for -15 and use dithering, it seems to be enough. Have to use Flats, though. I had some more time this weekend to shot same object (did 20 min. subs - the longest for me so far!). Hopefully will get more detail. Stay tuned!

Sharp image, NO darks subtract? I expanded image 200%, very sharp stars, good focus and tracking.
