You don't have to spend $$$$. I think a good stacking program is a must. Otherwise you bodge good data that you took so long to capture. When you think about the time needed to get good quality subs freezing your a** off, what's a couple of hundreds on CCDStack or other to do it right.
Don't get me wrong PS is great to color balance and bring out details in your shots but there's more to calibration, registration, normalisation, data rejection and stacking than aligning a couple of subs and matching stars manually in PS.
If you want to do some reading on all this I recommend Adam Block's tutorials at
caleum observatory. Needed skills well worth your learning IMHO.
