About

PixAstro turns the frames from your astrophotography session into a presentable final image, right on your iPhone and without needing to know the theory. Pick the folder with the frames from your ASIAIR, your camera or your capture software (USB drive, Files or iCloud Drive), or bring them straight from your ASIAIR's internal storage over Wi-Fi, and press Process. PixAstro does the rest: • Works out what each file is: lights, darks, flats and bias (from the FITS header, the name or the content). • Calibrates, measures the quality of every frame and drops blurry, trailed or cloudy ones. • Aligns the stars and stacks while removing satellites, planes and hot pixels. • Removes the background gradient, calibrates colour, stretches without burning out bright areas, reduces noise and stars and enhances local contrast. • Detects the kind of object (nebula, galaxy, cluster or Milky Way) and adapts the processing. Automatic mode, or Guided mode with sliders for every step, live preview and a before/after comparison. Every concept comes with a one- or two-sentence explanation. Made to be used next to the telescope: • Red night mode, so you keep your dark adaptation. • Works offline and never sends any data. • Your original files are never changed. Processing and adjusting are free. PixAstro Pro, a one-time purchase, unlocks saving the result as 16-bit TIFF, 32-bit FITS, PNG or JPG and sharing it. Formats: uncompressed FITS (mono, colour and Bayer), 16/32-bit TIFF, PNG and JPG. DSLR RAW files cannot be read on the iPhone yet; process them with PixAstro for Windows, macOS or Linux, which is free. Same processing engine as the desktop version.

What's New in PixAstro

1.6.0

October 31, 2026

• Frames straight from the ASIAIR. A new From the network (ASIAIR)… button in Your frames finds the ASIAIR on your Wi-Fi, lists its folders by date with last night's session already ticked, and copies the ones you choose to the iPhone. Nothing on the ASIAIR is touched. The ASIAIR only shares its internal memory over the network: frames saved to a USB drive plugged into it don't show up. • Cleaner background with one-sided gradients. When the sky is flat on one side and falls off sharply on the other (Moon or light pollution), the flat side no longer comes out with a bright band. • Dual-band filters: neutral sky. With an Hα/OIII filter (L-eXtreme, L-eNhance…) the sky no longer turns cyan.
