combining exposures
i am interested in how you combine exposures , as an example when imaging m42 at a long and high iso it will enevatably get a core burn out , i have seen that most people take a few at iso100 , a few at iso 800 and some at iso1600 and then combine them as to get a nice bit of nebulosity with surrounding areas and a detailed core.
i think this is done in photoshop but i have no idea of how it is done , does anybody have a good guide
many thanks colin
