Startrails Creator is an easy-to-use application to create star trail photos.

As light pollution become more and more severe, photographers no longer take extremely long exposure to get a star trail photos. Photographers now take a series of relatively short exposure photos, and use image-processing application to stack photos together and get one star trail photo. 

This process is boring and time-consuming, even with the help of image processing "macro"s. 

Startrails Creator makes this process simple and fast. With a few clicks, user can make a beautiful star trail photo without hussle.

Startrails Creator also have a relatively small memory footprint compare to the full-blown image-processing applications.

You can also create star trail animations and time-lapse videos in Animated GIF or Video with Startrails Creator.
