Comparison
NightScape Stacker vs. Starry Landscape Stacker
Starry Landscape Stacker helped establish landscape astrophotography stacking as its own category, and it has earned its reputation. The real question is whether stacking alone is enough, or whether you want the rest of your post-processing workflow handled in the same app, on any operating system you use.
Starry Landscape Stacker
Starry Landscape Stacker is a legitimate, well-built tool with a loyal following in the Mac astrophotography community. It was one of the first apps to treat landscape astrophotography as its own discipline rather than an afterthought of deep-sky processing, and that matters.
What it does, it does well. But it stops at stacking. After you have a stacked file, you still need separate tools to denoise, remove or reduce stars, and tackle gradient banding from light pollution. That means additional software costs, additional learning curves, and more time moving files between applications.
It is also Mac only, with per-device licensing. If you shoot on a Windows machine, or work across two computers on different platforms, Starry Landscape Stacker is simply not an option.
NightScape Stacker
NightScape Stacker covers the four steps that nearly every Milky Way landscape image requires after capture: stacking, AI denoising, star removal or reduction, and gradient removal. All four run inside one app, in sequence, using AI models that run entirely on your local machine. Your photos never leave your computer.
A single $99 license covers two seats with a perpetual license, with no annual renewals and no per-device restrictions. It runs on Mac, Windows, and Linux. If you have been pricing out Starry Landscape Stacker alongside a dedicated denoiser, a star removal tool, and a gradient correction tool, the total is likely to exceed $99 before you're done.
NightScape Stacker works with 16-bit TIFF files. Export from your raw processor first, then bring everything into NSS for the full pipeline before finishing in Lightroom or Photoshop.
One app. Four steps. Any platform.
