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.

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.

Great app!


How can you feather the paint brush when masking? The paint brush is set to the hardest edge possible and that makes masking a very time consuming and tedeous process. I saw in Ian Norman’s tutorial video that his brush was feathered and there is no obvious way to achieve that in the app.
Other than the paint brush feather issue this is a great app and very user friendly! I’ve achieved my best astro shots with the help of this app.

Thank you

Does okay but...


I like the application and it does do a really good job at stacking my astrophotography, however, I really dislike the fact that it takes the liberty to make changes to the exif information for advertising. If I was using a test version, okay, but paying 40 bucks and having it advetise isnt what I would expect from „paid“ vesion of software.
