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.
I have three images trying to stack them together. All are products of APP stacking:
- Extracted Ha stack
- Extracted Oiii stack
- RGB stack
I load them as Lights and then at 5) Normalize:
Encountered error in module: OverlapBetweenTwoImageObjectsCreatorWorker Error message: java.lang.ArrayIndexOutOfBoundsException: 1 Cause: 1 java.awt.image.ComponentSampleModel.getSampleDouble(ComponentSampleModel.java:872) java.awt.image.Raster.getSampleDouble(Raster.java:1690) G.a(Unknown Source) G.doInBackground(Unknown Source)
Then when I uncheck [] neutralize background, I get this:
Encountered error in module: OverlapBetweenTwoImageObjectsCreatorWorker Error message: java.lang.ArrayIndexOutOfBoundsException Cause: null no trace
Any ideas what is going on / how to make it work?
This is all on the latest 1.083.4 / Windows.

Yes, this is because APP can't normalize narrowband data together with RGB data yet (it's on our shortlist to make that possible). So you would need to have those stacks registered with each other and saved, and then you can combine them in RGBCombine.
Thanks, but not sure if I understand you correctly.
The RGB is from a different session/optics/camera, so I need _somehow_ to register it with the other two narrowband images.
So should I make an RGB of combined Ha+Oiii and then register it with the RGB?
I have just tried the 1st step - RGB combine of the Ha and Oiii and goth the following:
The images aren't compatible! please make sure that the data has same dimensions and bit depth
Both the Ha and Oii are APP products of "Extract Ha" and "Extract Oiii" from the same dual narrowband bayer stack.
What do I miss?

Did you register and then save the registered frames? Saving those can be done in the register tab all the way down. It's the normalization that can't be done.
No I haven't saved the registered frames.
I went all the way through to Integration with each of (Ha, Oii, RGB).
Should the steps be:
- Extract Ha -> Load -> Calibrate -> Analyse Stars -> Register -> SAVE
- Extract Oiii -> Load -> Calibrate -> Analyse Stars -> Register -> SAVE
- Load the SAVEd as Lights and Normalize?
or
RGB combine the SAVEd frames
?
I'm lost a bit now...
No, just create the integrations first. The Ha, the OIII and the RGB and load those integrations back in as lights, then register those and save them.
Ahhh OK got it. It works now - shows the aligned sessions after RGB combine. Thanks a lot for the guidance!

No problem, great it did!
