Copies Files Only When Ready
AstroFileSync checks that a file has stopped changing and is fully available before starting a transfer. This helps prevent incomplete or corrupted backups without interrupting the imaging session.

Windows Tools For Deep-Sky Imaging
Download practical astrophotography software for safer capture nights, faster frame review, and cleaner deep-sky imaging workflows.
This tools hub currently includes AstroFileSync for automated file backup and Astro Frame Selector for scientific subframe analysis before stacking.
ASTRO FILE SYNC
Built for long imaging sessions and unattended backup workflows.
AstroFileSync works especially well alongside NINA, but it can be used with any capture application that writes images to a monitored folder.
The synchronization engine runs as a Windows Service, allowing it to continue working quietly in the background even when the dashboard is hidden.
Designed For Capture Nights
The app is lightweight enough for imaging computers running NINA, PHD2, guiding software, device-control tools, and other astronomy utilities at the same time.
Verified Backups
Optional SHA-256 verification can confirm copied files after transfer, adding confidence when backing up valuable subframes during a long session.
Drive Reconnection Recovery
If a destination drive or network location becomes unavailable, AstroFileSync can recover when the destination comes back online.
Deep-sky frame quality analysis
Astro Frame Selector
Free Windows x64 application
Astro Frame Selector is a free Windows application designed to simplify one of the most repetitive parts of deep-sky astrophotography: deciding which light frames are actually worth stacking.
It analyzes an entire imaging session automatically, measures multiple aspects of image quality, compares frames within the right session and filter context, and helps separate them into Keep, Review, and Reject categories.
In plain terms: Astro Frame Selector is an astrophotography frame selection tool for Windows, built to reduce manual subframe inspection without blindly sacrificing good data.
Scientific Decision Engine
The app evaluates focus, FWHM, PSF quality, star shape, tracking, motion, noise, gradients, transparency, clouds, and calibration anomalies instead of relying on a single score.
Keep / Review / Reject Workflow
High-confidence frames can move quickly into Keep or Reject, while uncertain or borderline exposures remain available for human judgement.
Autonomous Session Selection
Version 7 introduces safe automation signals that show how much of a dataset can be handled automatically and how much still deserves attention.
Offline Personal AI
A controlled learning system can adapt recommendations to your decisions while keeping astrophotography frames local with no cloud upload required.
