Does anybody know of software that could batch report average pixel value and other pixel stats for a sequence of images?

I want to use an SLR to record variation in sky brightness over the course of a night and between nights. ie. I don’t want to have to open each file and manually enter pixel statistics for thousands of images into a spreadsheet!

The reason for doing this is to get some objective measures of ‘dark sky’ and how it varies. eg with some of my timelapse footage, I think I am starting to see structure and variation in airglow, but I need a bit more evidence to draw the right conclusions.

Cheers
