Software Product Description

DeepSkyStacker is a freeware for astrophotographers that simplifies all the pre-processing steps of deep sky pictures.
  • Registering
  • Stacking
  • Simple post-stacking processes to quickly view the final result.
  • Saving the resulting picture to a TIFF file (16 or 32 bit)
After a shooting night you give all your pictures (light frames, darks frames, offset/bias frames, flat frames) to DeepSkyStacker and you go to bed. The next morning (or is it afternoon?) you can see the result and start post-processing.


  • Automatic registration of a set of pictures
  • Automatic detection of stars using all the picture area
  • Preview of registered stars
  • Sub pixel registration
  • Automatic derotation
  • Automatic creation and use of offsets, flats and darks frames
  • Sub pixel alignment and stacking
  • Supported bitmaps formats : 8, 16 and 32 bit colour and monochrome TIFF files, 8, 16, 32 and 64 bit colour and monochrome FITS files, JPEG, BMP, PNG
  • Native use of RAW files from most DSLRs (CR2, NEF, CRW, ...) without using an intermediate file format (TIFF or other).
  • Darks, Flats and Offsets computed from and applied directly to the RAW picture before any interpolation.
  • Stacking methods: average, median, kappa-sigma clipping, auto adaptive weighted average, entropy weighted average, maximum...
  • Preview of all pictures (including RAW)
  • Simple post-processing with RGB levels, luminance curve and saturation adjustments.
  • Save the resulting picture to 16 or 32 bit TIFF files with or without adjustments applied.
  • Simple and intuitive user interface
  • Optimal memory usage: the same amount of memory is required to register and stack 10 or 500 pictures.
