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

Perhaps Process Container might help?

ProcessContainer along with ImageContainer I think will get you what you need. The first to set up the processing steps, the second to create the "image" to apply it to using the contents of a folder. I think in practice you have your processcontainer icon on your desktop and you open your image container and just drag the process onto that to apply it to all your defined images in that folder.
