New improved internal memory controls should now work on all computers
May 1 2026: APP 2.0.0-beta43 has been released !
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...
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.
I've done a few processing runs using LNC , and processing has taken a very long time. This morning I'm working on a stack of 40 DSLR frames using 4th degree LNC and 3 iterations. After working more than four hours on the data, the Integration step is only 50% complete. My machine is very capable -- Win 10; 6 core 3.70GHz CPU; 32GB RAM; a good graphics card. Are long working times like these to be expected? Adding DDC adds much more processing time. Thanks.

The obvious question is: why do you enable LNC, particularly 4th degree LNC and 3 iterations? What do you expect to gain with that?

@wvreeven I have resolved processing-speed issue.  But to answer your question: I'm processing a series of 42 DSLR images of the NEOWISE comet with strong color and brightness gradients, images shot in multiple sessions with changing light near dusk. LNC and advanced normalization is suggested for this situation.

@jehoener Yes that of course is a valid reason to use LNC. I was merely asking so I may learn from your reasoning.
Congrats on solving the processing-speed issue! How did you manage to do that?

Thanks, Wouter
@wvreeven Wouter. I have a new computer with multiple internal hard drives. I was running APP on the C drive while my data was stored on the D drive. I learned that temporarily moving the data I'm working on to the C drive will allow APP to process it much faster. MUCH faster!
I also made the mistake of transfering files at the same time from an external USB hard drive to an internal drive. I didn't know that doing that would interrupt the CPU's work on APP and slow things down considerably.
Thanks for sharing the reason! Yes APP writes a lot using the disk for processing so the fastest disk and access to it is recommended. Probably the simultaneous writing going on in the background was the biggest factor?
