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 1.6.4

Fixed an error that caused alignment to fail if both the time between the exposures was too large (30 to 40 seconds was probably the limit) and the EXIF data did not have the sensor resolution (many cameras include this information in the EXIF data, but some cameras and/or RAW processors do not).

Starry Landscape Stacker is now more tolerant of inconsistencies in alpha channels generated by ON1.

Very happy

I have used this only 2 times and it works flawlessly. My first attempt was with the Milky Way and mountains in the foreground. My second usage was with the Orion Nebula. I had phenomenal success with the Milky Way shot and am struggling with my Orion shot. I am quite sure my struggle with Orion is the pictures I’m dealing with, not this software. The difference in dark areas between a raw shot and using this software to combine 10 images is amazing. Snow fields are quite grainy in the individual shots, smooth as silk in the final output. Does exactly what I wanted it to do.

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
