AstroStack is an easy-to-use astronomical imaging and processing tool geared towards the use of inexpensive webcam CCDs. It provides a very tunable environment to produce the best quality images. Supports the following features:

  • Tunable webcam sampling.
  • Image stacking (averaging, additive etc.).
  • Pre and post-capture gamma (brightness) and contrast correction.
  • Dark-shot CCD calibration (subtractive).
  • An internal 16bit grey-scale format for optimal resolution.
