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:
- Global star alignment (rotation + translation)
- 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
- Plate-solving is 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
