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.
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).
