Hey Mohammed,
I've taken this approach many times and it's definitely do-able. Stacking in DSS (Deepspace Stacker) is the best way to go, then edit it in Photoshop (Im assuming your proficient with CS and post processing). Stacking in DSS removes any rotation and automatically aligns your images. If you haven't used it before, it does take a little while to figure out whats going on, but its extremely powerful.
I'm not sure what you experience in Photography is like, so do excuse me if I sound up myself
but always remember to shoot in RAW, as stacking in RAW in DSS gives you much more flexibility and stretching ability.
Best of luck! Do post your results here
