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.

Are there any quality drawbacks when using higher degree order i LNC?

@digitaliz-se Hi Stefan,

When you hover your mouse cursor over the LNC degree select box, you will see the following info:

Does that answer your question?

@wvreeven Not really. I was hoping to use 4th degree because I thought it would get better result than 1st. I assume that integration time and memory consumption will sufier instead.

@digitaliz-se Yes, integration time will be longer. Memory not per say. The instructions indicate that you should start at 1st degree and slowly increase. It is impossible to say if your data will be better with 4th degree or not without trying.

Why do you want to use LNC and why at such a high degree?

@wvreeven More complex math to solve the problem should yield a better outcome. That is  what I try to tell myself.

@digitaliz-se And what problem should the math solve in this case?

Just better flat illumination since I shoot in a polluted area all night and all directions differ in LP, espeically when doing multisessions and stacking with different telescopes and filters.
Just curious if it would yield better image quality. Hard to tell in the final stack before you really stretch it. I’ve had good results just using 1st order of LNC. I always use LNC even if I only stack one session using same equipment. I’ve found it to yield better result than not doing LNC.
