What does stacking do for astrophotography?

Reduced noise in an image due to low light, high ISO. Software (Sequator for Windows, Starry Sky Stacker for Apple) align the moving stars while also keeping landscape aligned.

Thanks for the explanation. I've always been entranced with the Milky Way in the night sky.

Is there a piece of sofware to enhace star trails?

There are two methods for star trails: multiple short exposures (say 30sec, f/2.8, ISO 800) which are brought into Photoshop as layers, and then combined with the layer “lighten “ setting. there is also a freeware package (Startrails.com) The second approach is one long exposure (45 min, f5.6, ISO 320) which only needs Lightroom or any other basic photo processing software to enhance (including the packages supplied with Canon, Nikon and other camera suppliers). The negative of this approach is any unplanned light from anyone will ruin the entire shot. With the multiple image approach, you can just not include any light destroyed images from the final. There are a lot of YouTube videos on Lightroom Milky Way / Star trail processing. I prefer a set of Lightroom presets which walk you down a road map of steps, selecting each one (white balance, exposure, contrast, shadows, etc. to your liking.
