Stacking just dousnt make sense to me

[firefite]

So as the title says i can't get it to work for me . i have some decent star photos. I read up on how stacking can make the stars much brighter and look better but i want static star photos no trailing. so how do i accomplish this , I've tried with Zerene Stacker but its gives me trails. any help would be great

This isn't something you can do at the software stage, its something you have to do at the capture stage. In short the world rotates, thus if you keep your camera in the same position whilst taking a long series of photos you'll end up with the stars moving over the sky. When these are stacked you get your light trails.
To counter you need a special equatorial mount - either manual or motorized - to allow the cameras position to be changed as the stars move so that you can track them through the sky.

the other option is a single photo with a very long exposure (with the tracking mount again) however that would likely have to be motorized and require a very sturdy tripod and also some kind of custom advanced cooling for the sensor to prevent heat build up (and that all likely runs at a high budget)

kk I've herd of the mounts , just thought you could stack shorter 10-15 second exposures to get that nice bright look

Hmm have you had a read of this thread here http://www.thephotoforum.com/forum/articles-interest/276016-shooting-night-pictures-stars-stuff.html

I've not read it in any depth - but it might have some answers/clarifications for you.
