post procesing, multi camera subs

[mislav]

hi, is it possible to stack subs that are taken with diferent dslrs and diferent iso and exposure? I am asking because of combination of full spectrum camera, and lower iso standard camera to combine stars and fogs.. If high iso and exposures are taken stars getting big, i tought to try combine two diferent setups-is it possible?

It is, yes. (I think that by 'fogs' you mean 'nebulae' in English.)

I find Registar https://aurigaimaging.com/ to be the easiest programme for combining data from different scopes and cameras. Sometimes I will just use Registar to co-register the data from two cameras and I will do the final blending (stars from one, nebulae from another, etc) in Photoshop using Layers.

As long as you calibrate each set of images seperately. That is, each set should have its own bias, (dark, ) and flat frames.
