I have a big problem with dynamic range in my DSLR pictures of the sky. The contrast range of pictures on a DSLR is 256 levels. That's a range of around 6 magnitudes. To look at very faint objects, I have to expose a picture to place a faint object so that it is a reasonable number of levels above black, if the statistics of stacking are going to help. Any picture - particularly a wide field picture - is going to include mag 2 or 3 stars in it, which are going to burn out. The stacking process can yield a bigger contrast range if it gives a 16bit image but how to get rid of the gross white blobs? Do I really just have to edit them out and insert those stars from a lower exposed image? I guess the answer has to be Yes. But some of those bright stars are bang in the middle of some Nebulae. ???? What must I do to make the resulting picture look like 'the truth'?
