Hello to all,
to thank you for your comments, is a great achievement by Italy, in these areas, the seeig is poor, and it is very difficult to capture good images. This image is the result of an acquisition of 2,000 frames to 7.5 fps, for alignment, I used Registax 4 and used about 1600 frames for stacking and processing end.
See you soon, always follow your work, good luck!
