I was wondering if you (Ivo) have plans for eventually including a module that could combine different sized files. The reason I ask is that many of us use different cameras, and as a consequence, the data files are different sizes. It would be nice to be able to glean the best files from different sessions, and combine them.

Maybe there is some kind of program out there that already allows this, but I am not very good at searching for such.

Anyway, after some 7 years of doing photography, off and on, I have accummulated about a terabyle of data, that might have some good data in it to use for the future. CaleyAnn

That would be part of a stacking solution for sure.
I believe Astro Pixel Processor might have the sort of functionality you are looking for with regards to combining data files of different sizes.
I think there's a free trial - perhaps worth a try?
