Max, CCDstack is not a quick way to become "like them", it just has a function that makes it easy to set white/black points so you can get on with the rest of your processing in PS which I think is what you originally asked for. It has a lot of other great functions as well but that is irrelevent here. You might like to take a look at Adam Blocks website for more info on CCDStack and what it can do. He also offers a great tutorial series (on DVD) based on using PS for processing astro images.
