June 24 2026 APP 2.0.0-beta46 has been released !

Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.

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.

Hello,

Is there a tutorial or instructions on how to split Ha and OIII from OSC while using a dual band filter?

 

Thank you

@stephanhamel22 Hi! This is quite simple. Load your lights and calibration frames in tab 1. Then in tab 0 select the Ha - OIII extract Ha algorithm. Then go to tab 6 and click integrate. When done, return to tab 0 and select Ha - OIII extract OIII. Click yes when asked if you want to normalize again and in tab 6 click integrate once more. That’s all.

Thank you for this.

 

How does that method compare in terms of fina result with extracting RBG from the same fit files?

@stephanhamel22 Mabula has optimized the extraction of the Ha and OIII signals from dual band images so using those algorithms will yield a better SNR than extracting the color channels from RGB integration results.
