FAQ

The trail is removed but the stars on it are gone in other tools. Here?

They're kept. The trail's light is subtracted rather than painted over, so a star sitting on the streak comes back through the subtraction. Check at 1:1 — that's the whole point.

Do I need a stack of exposures?

No. It works on a single frame. If you do have a stack, clean each sub or the integrated result — your choice.

What files can it open?

16-bit TIFF (the Lightroom round-trip format), plus DNG and common camera raws (ARW, CR2/CR3, NEF, RAF, ORF) and JPEG/PNG. It writes 16-bit TIFF with your EXIF and colour profile preserved.

macOS says it can't verify the developer.

On a first direct-download launch, right-click the app and choose Open. The Mac App Store build won't show this.

Windows SmartScreen warns about the installer.

Fresh installers build reputation over time. Choose More info → Run anyway. The installer is per-user and needs no admin rights.

Is my data safe?

Everything runs locally — no uploads, no accounts, no telemetry. See the privacy page.
