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.

Hi Mabula,

You mentioned this in one of your tutorials. How would you go about using an RGB image to color calibrate the stars in a Narrowband image?

Dear @Whixson,

I am not entirely sure what you mean here. Do you mean that one would use a broadband image to correct a narrowband image?

Regarding Star Color calibration with the Black Body models: it can't be done on narrowband data. A Black Body model needs broadband data to be able to work properly.

So in the case of Narrowband data, you will need to use the RGB balance model in the Star Color Calibraiton tool. Then use HSL Selective Color for final tweaks 😉
