I am on a mac and I have found a stacking program (starstax). I have had decent results, but I don't see much of a difference between that and photoshop. I know a few people use startrails for windows, and I could install that on my other system, but is it worth it? Are there any features I can't do with Photoshop? I like star trails, but can I use stacking to bring out galaxies and other things?

IMO, stacking is more useful for DSOs than it is for trails. It allows you to see things you simply can't see without it.

So how do you shoot for and stack for DSOs? I can see the milky way really well and I would love to try that. I did notice in my stacking there is a subtract feature that removes the stars.

If you have an accurate goto mount, you just tell it where to go, and start shooting. If not, then it gets rather time consuming as you point where you think the object is, take a long exposure and see if you got something. When I did M51 and M101 (see the "M51 at 400mm", and "M101 at 400mm" threads), I would do a 15 or 30 sec shot, and when I saw a faint smudge in the frame, I knew I was close. Then I took a few more shots to center the smudge, and then finally started my real data collection shots.

Then stacking all those frames turned the faint smudges into gorgeous galaxies.
