In this Astrophotography Tutorial I discuss how to stack short exposure images in Photoshop to reduce noise. This is a helpful technique for anyone wishing to align their star photos to increase the signal-to-noise ratio.
Many photographers are limited to short 30 second exposures in their night sky photos. However, you can pull a surprizing amount of data from your subject matter by stacking multiple files together using Photoshop.
This tutorial uses Adobe Bridge, Adobe Camera Raw and Adobe Photoshop to accomplish the task.
