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.
First off I love the ability to do this extraction. However, it would be nice if that can be selected as a filter, and than it actually uses that information to do the extraction for both of them. Currently the workflow to do the extraction is a bit cumbersome as you have too do 2 extractions, than you need to combine them. I would love to see this workflow get some much needed love as it is a fantastic feature.
@romonaga Thanks for your comments, Robert. Improving the Ha/OIII extraction is on the TODO list. I am not sure if it will be part of APP 2.0.0 and if it isn't then it will be for a release soon after that one.

I have a question regarding that. i usually do the Ha-OIII Color extraction. How is the third (blue) channel composed? I use that so I can do a fake SHO palette.
But as I understand, it’s better to extract them and then do the combination?
How do I get the third channel?
It is cumbersome to extract Ha and then OIII and then Ha-OIII to get the the blue channel.
I’ve seen videos that extract the mono channel and make that the third channel. Which would be the best route to choose?
The easiest is the way I do it now, Ha-OIII color -> Split channel -> RGB Combine

@digitaliz-se Both the Ha and OIII channels are mono channels. To create a color image, you can use the HOO formula in the Combine RGB Tool. That means that Ha will be used for the Red and OIII for both the Green and Blue channels. There are ways to create a synthetic third channel and using that for Red, while using Ha for Green and OIII for Blue to create a fake SHO image. APP doesn't have a specific way for doing that but you can search on internet and then apply accordingly.
HTH, Wouter
