New features are being introduced quite regularly. Here is a list of main features:

  • Native image format support
    • unsigned 16-bit FITS files (other FITS are converted to this format on-the-fly)
    • SER files
    • AVI and many other film files
  • Image conversion (to the native FITS format only)
    • Supported input types: 8-bit and 16-bit BMP, TIFF, JPEG, PNG files, NetPBM binary images, RAW DSLR images.
  • Image registration; supported methods:
    • Translation using DFT centered on an object, generally used for planetary images
    • Translation using PSF of a star, generally used for deek-sky images
    • Manual translation with two preview renderings of the current image with reference frame in transparency
    • Image rotation and plate-solving are not implemented yet
  • Image stacking
    • Summing
    • Median
    • Percentile clipping
    • Sigma clipping
    • Median sigma clipping
    • Winsorized sigma clipping
    • Linear fit clipping
    • Pixel maximum
  • Pre-processing of images with multi-channel offset, dark and flat images
  • Enhancement of final images: lightness/contrast cursors on each layer, different scaling modes (linear, log, square root, squared, asinh, histogram equalisation), negative and false colour rendering and clipping.
  • A command line for various processing functions, see the list of available commands.
  • A star finding algorithm with PSF information
