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 1.9.8

Fixed a problem that would cause Starry Landscape Stacker to crash during the alignment phase if the image files did not have a capture time and there was not enough memory to process the images in memory.

Fixed a problem in some warning messages where the “Ok” button would be hidden if a large number of image files were being processed.

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

Developer Response ,

Thanks for your feedback. I am glad you have had success with it. I am not sure how Ian Norman's tutorial showed a feathered brush. SLS has never had a feathered brush. The edge of the mask has to have a hard edge--feathered alignment just does not work. I am not sure how having a feathered brush makes it easier to make a mask. Perhaps you could contact me directly and we can find a way to make masking easier for you. Launch Starry Landscape Stacker, and under "Help" in the menu bar select "Email Developer".

Updated review

So my last review was August 10th and since then the app has had a few updates and it keeps getting better.

There's now the option of doing noise and color noise reduction directly in the app and I've tested it by doing that and then not doing it and doing the noise reduction in photoshop and it looks like the noise correction in SLS is better!

It seems the masking has gotten better too. Most of my shots have trees and it used to be a pain but it does a mighty fine job. I also love how it will automatically reorient images becuase often after I shoot light frames I will set my camera to take 30 dark frames and then pack it up in my bag as I walk back to the car and if the camera turns it will think I'm taking portrait shots. So it's a huge help that I don't have to go in and manually reorient the shots before using the stacker.

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.
