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 1.5.0

- If you have an image where you like the way the stars are lined up with things on the ground you can select this image to be the one that the others are aligned with.

- Four different compositions are computed and can be saved. This makes it easier to include satellites and meteors in a final image created with an image editing tool.

- There is a check box at the bottom of the open panel to force classification table to be displayed.

- In the classification table, clicking on a column heading now changes the classification of each image that can be change to that classification.

- Improved efficiency of memory usage--typically more than a 50% reduction in peak memory usage.

- Performance improvements--typically more than 2x faster alignment than SLS 1.4.5.

- Huge improvement in redraw performance resulting in much faster scrolling, zooming, painting, erasing and adjustment of viewing parameters.

- The alignment algorithm is much more tolerant of widely varying sensor and lens characteristics.

- Other minor improvements and bug fixes.

Customer Reviews

Works well and as advertised


I’ve used this program primarily for stacking astrophotography images taken with a telescope and it works very well. It’s rejection of satellites and airplane trails is particularly useful . The only limitation is it rejects image sets that are taken too many minutes apart but that can be worked around. The program improves with each update. Support is also useful and responsive the one time I asked for it.

Starry Landscape Stacker


This application is a must for anyone serious about generating high quality digital files of the night sky with stars.

After a few second of capture time, files will show star movement; this motion is more apparant as the focal length increases (more zoom). One can shorten the capture time by increasing the ISO, but at some point too much ISO noise is generated. Starry Landscape Stacker eliminated the problem of blurring stars, assuming they are shot in focus, using software that stacks multiple images taken at short shutter speeds (around 10 seconds) and very high ISO (up to 12,800). WIth a little practice you create terrific star files in under a minute, assuming you have 8-10 high quality files to work with. This software is worth every penny. On top of that, support by the developer in the form of tutorials and email response to questions is first rate.

Must have for night photography


I was seeking solutions to reduce noise for my Milky Way shots, and the search lead me to this application. I was amazed at how much noise was reduced by simpily taking multiple shots and stacking them. This is a must have application if you’re into Milky Way photography. The program is simple to use and gets the job done. The newer version can also load a mask created from photoshop. Since I have to create a mask in photoshop anyways, this feature saves me from having to create a mask in Starry Landscape, and it simplifies my workflow even more.
