May 27 2026 APP 2.0.0-beta45 has been released !

Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options

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.

When I run pure Ha and Oiii algorithms on my OSC frames because of using the Optolong L-eXtreme filter, can I use the same master calibration frames from the first run of Ha for example when I do the second run for Oiii or should I have APP re-create the master calibration frames for each run when using the narrow band process to get to the calibrated light frames?  I'm not sure the Ha algorithm verses the Oiii algorithm has any impact on the calibration masters or just affects the calibrated lights?

@j1will Hi John, APP will use exactly the same calibration frames so no need to create new ones. Simply run APP with the extract Ha algorithm selected in tab 0 and, when done, select extract OIII in tab 0 and return straight to tab 6 to click on the Integrate button and you’re set.
