First of all i wanna say tanks to all community of ML. your firmware rock!
I am new in astrophotography and sometime I got wrong pictures because I over exposure the subs. So, to take good subs in astrophotography, the luminosity histogram should be placed 1/4-1/3rd from the left (range 0 to 255). How can I get the mean and dev.St value of the luminosity peak?
thanks for your suggestion
