What is AstroLens?

AstroLens is a specialized open-source tool developed by Deep Field Labs designed to assist astronomy enthusiasts and researchers in analyzing and visualizing astronomical imagery. The application offers modern algorithms and AI-assisted features to identify subtle details in celestial captures and streamline image evaluations.

The platform processes common astrophotography file formats such as FITS and TIFF directly within the browser. Users can adjust contrasts, analyze star profiles, and execute automated noise reduction and object identification workflows.

As a freely accessible tool, AstroLens targets both amateur astrophotographers and scientific researchers seeking a lightweight, transparent solution for image analysis. The open-source development model allows for custom modifications and community-driven enhancements.

Core features & strengths

  • FITS and Image Analysis — Allows users to load and thoroughly inspect astronomical FITS files alongside standard image formats directly in the browser.
  • AI-Assisted Object Detection — Utilizes algorithms for automated identification of stars, nebulae, and galaxies in complex deep-sky imagery.
  • Interactive Visualization — Provides flexible stretching methods and color correction tools to optimally render faint astronomical structures.

Who is this tool for?

AstroLens is designed for amateur astrophotographers, astronomers, and physics students. It is ideal for anyone looking for an accessible, cross-platform solution to inspect celestial imagery.

Typical use case

An astrophotographer has captured an image series of a faint emission nebula and wants to inspect the quality of individual frames and star sharpness. Using AstroLens, they import the FITS files into the browser, analyze star profiles (FWHM), and let the tool highlight key features and background noise. This saves significant time during the initial preprocessing stage of astronomical datasets.

When a different tool fits better

The tool is not intended for general image editing such as portrait or landscape photography. For heavy batch stacking operations or advanced scientific photometry workflows, specialized software suites like PixInsight or Siril are recommended.
