I have Subs on a Target for multiple nights, some using one ASI mono camera and some using a different ASI mono camera with different file size and resolution. When I try to process them in Pixinsight using the batch preprocessor it yields two Master lights for each mono color Channel instead of one. It makes one master light for the higher resolution camera and one master light for the lower resolution camera for each color channel. This essentially means each Master only has half of the data whereas I want it to have all of the data. I have found no way to merge these two Master lights.
I have tried image integration and every other tool that makes sense. Nothing works. I have run the batch preprocessing again and it yields the same result- two Master light files instead of one for each color channel. A friend has told me that PI will merge Subs from two different cameras no problem but it does it during stacking. Not so with batch pre-processing.
How do you do it?
