Read more about this major release...

v2.0.0 is a major release with much better performance, especially with larger images and on lower end hardware. The new support for FITS is experimental at the moment, as FITS is a complex format. The goal is not to produce a fully featured image processing suite, but to be able to display FITS images with reasonable auto-stretching to quickly identify and weed out unusable exposures before stacking.

v1.7.0

  • New cameras supported: Canon R5C, Canon R5 Mark II, and more.
  • Added `/windowed` parameter to start in windowed mode.
  • Add support for new Canon COLORDATA version 64.
  • Fixed endless loop in BMFF parsing.

v1.6.0

  • New cameras supported: Panasonic DC-G9 II, Canon EOS R100, Fujifilm X-T50.

v1.5.0

  • New cameras supported: Canon EOS R8, DC-S5M2 and DC-S5M2X.
