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 1.8.0

Display update for almost all tasks is much faster, especially for MacOS 10.14 (Mojave) and later.

Pinch zooming is now supported.

Zoom level is displayed as a percentage, and can be typed in.

Undo/redo of painting and erasing of red dots is by stroke (mouse down to mouse up) rather than by individual point. This should be faster and more convenient for most users.

Alignment and composition is typically more than 2x faster than version 1.7.

Improved alignment where there are few stars to align (e.g., corners with vignetting).

Changing images (with next/prev and arrow buttons) can be slightly slower. (This is a trade off with faster drawing in general).

SLS can no longer align images where the camera moved so much that you can see movement at the horizon in the images.

Other bugs fixes and UI improvements.

Starry Landscape Stacker now requires Mac OS 10.10 or newer. (Was 10.8 or newer).

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!!

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.

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.
