New features are being introduced quite regularly. Here is a list of main features:
- Native image format support

- SER files and FITS cubes for one-file sequences
- AVI and many other film files, their support is being dropped in favour of SER.
- 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.
- Pre-processing of images with offset, dark and flat images, cosmetic corrections and synthetic offsets
- Image registration; supported methods:
- Global star alignment, based on star detection and matching using a variable number of degrees of liberty
- Translation using DFT centred on an object, generally used for full-image planetary images
- Translation using PSF of a single star, generally used for deep-sky images or photometry
