ISO ladder for astro
1

I hope this ladder helps illustrate the best ISO to use for astro imaging.....I tried 400-5000 in 1/3 ev steps and found 640 came out best with 400 a close second, and 1250 and 2500 right behind those.  What do you think?

In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.
-Dwight D. Eisenhower, 1961
