Improved internal memory controls (much more stable and faster on big datasets), fixed CPU image viewer, fixed Narrowband extraction demosaic algortihms.
Apr 29 2026 APP 2.0.0-beta42 has been released !
New improved Normalization engine, Fixed random crashes in integration, fixed RGB Combine & Calibrate Star Colors, fixed Narrowband extraction algorithms, new development platform with performance gains, bug fixes in the tools, etc...

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.

Hi there,
Can someone help me here?
Why do I have such extreme areas in magenta in my picture after the starcolor calibration? 🙁
BTW: I used a dual narrowband filter for this image, but i think this is not the problem.
Best regards
Stefan 🙂

Though I've not seen such an extreme result yet, it in fact is a problem to color calibrate narrowband data. The color calibration needs broad spectrum data, because it works on the assumption it sees this from the stars in the image (black body radiation). Narrowband data you need to tweak yourself regarding the color. Sometimes you can be lucky and it produces something you like, but it won't be accurate.
