Pixinsight batch image division

Hi,

I have a set of 50 images and I need to divide each one of them by another image (always by the same image). I can do it one by one with PixMath but that will take forever. How to do it more efficiently?

A bit of background: I am playing with the light panel for flats and want to test its uniformity, as described here.

I have taken images with camera at 0 and 90 degrees and then I have to:
1. Dark subtract each image (can use ImageCalibration)
2. Divide each image in the first set of images by a sigma-combined stack of the second flat series - How to do this efficiently?
3. Median (or sigma clip) the first stack of images (can use ImageIntegration)

Thanks in advance
