Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

Astro Pixel Processor 1.036.0
- SPEED, all data interpolation algoritmes are further optimized. Especially Lanczos has a huge speed up, a factor of 300%. This will increase stacking speed of lights frames significantly.
- SPEED, OPTIMIZATION, all coordinate transformations (in registration engine) have become much more memory friendly, increases speed by reducing overhead.
- IMPROVEMENT Nearest Neighbour and Bilinear data resampling are now optimized for downscaling operations as well.
- IMPROVEMENT Image viewer now properly shows images with a correct downscaling algorithm. Result, images look much less noisy and rejection maps have much better visibility for airplane/satellite stripes.
- CHANGED, IMPROVEMENT auto DPP parameter calculation is much faster and the stretch parameters are a bit more conservative. The background target is now set at 0.175 of the data range. It used to be 0.25. And the dispersion target is now at 5 * dispersion, used to be 3 * dispersion.
- SPEED, drizzle integration is now a lot faster (about 4x times) by optimizing memory usage and data lookup.
- FIXED, drizzle now works correctly in compostion crop mode.
- FIXED, registration, the multiple view complex distortion modelling can hang when the "same camera and optics" option is turned off, in the case of data which really needs this setting to be turned on or when all the light frames have a very similar field of view. The regression seems to hang, because the regression keeps finding better solutions, which are unstable and unrealistic solutions.
- NEW, normalization, you can now save your normalized frames, with or without registration parameters applied. Requested by Dominique, (so you can normalize your data and use Adaptive Airy Disc debayer on RGB data before doing comet alignment with DSS or PI, since APP doesn't have a comet alignment option yet...)
- FIXED, preview filter 8bit saturation error (mabula)
