Starry Landscape Stacker makes it possible to produce landscape photographs taken at night that have both low noise and stars rendered as points. It does this by compositing several images taken in rapid succession, shifting the sky as needed to align the stars. A free trial version is available on the developer's website.

What's New

Version 1.6.2

Light frames may now have alpha channels. This is important for users of RAW converters that always include an alpha channel even if there is no mask. (For example, ON1 and Photos alway include an alpha channel). It is strongly preferred to use tiff files without alpha as the files are 33% smaller and more than 33% faster to read. There is a new restriction—if all of your images have an alpha channel and you want to supply a mask that marks the whole image as sky, that mask file must be a monochrome bit map.

Fixed some problems with handling of the boundary between sky and ground. Image quality in this area is much better.

Fixed some errors with computing and reporting required temporary file space.

Fixed a problem dealing with incomplete EXIF data from some older cameras.

Seems to do what it says.


I’ve only used it for about 5 minutes, but it seems to work well. Only tested it with a three shot stack. The program doesn’t seem to run DNG files, but will run TIFF. The interface is easy to use and is fairly intuitive. Noise reduction is noticable on pictures after stacking.

Great job!

Starry Landscape Stacker is amazingly easy to use, and does a fantastic job. The program chews through 20 tiff stacks with ease, and provides significant noise reduction while lining everything up perfectly.

Excellent Software


I bought it thinking it may not work as described for the price… I was very pleasantly surprised!! It works as described and is super easy to use even though it’s doing some complex work in the background. Definitely worth the purchase!!
