Apr 9 2026 APP 2.0.0-beta40 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! 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. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...
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, first try with Beta22 and on the final Integration Im getting this error box
Any ideas ?
EDIT by Mabula: solved in 2.0.0-beta23
Could you explain more about the type of data you were processing and the workflow?
Hi @russ-telfer,
Thank you for reporting this, I will investigate immediately and will report back later.
One question, is this occuring on Windows, or?
Mabula
Hi @russ-telfer,
Can you give more information? What kind of data are you processing? Multi-Filter perhaps? Or Multi-session, or both?
Mabula
@mabula-admin Hi Mabula
it was on a Windows 11 (fully updated) PC. Yes it was adding recent Oiii data to existing Oiii and Ha data. It first crashed when finally integrating the original Ha although it did save the stacked Ha Fits. I then tried it with just the Oiii (latest 58 subs with the original 70+subs) and it crashed about half way through ‘writing to mapper’. If I ran with just the latest data it integrates fine, so it seems to be a multi session issue
Hi Russel @russ-telfer,
I just did some tests with multi-session and everything works fine here, so I need more information and probably your data to understand what is happening.
How do you load the data of the sessions and what settings do you use in 6)Integrate to integrate the sessions, the Multi-Session options at the top in menu 6) ?
Can you upload the data here:
https://upload.astropixelprocessor.com/
username : uploadData
password : uploadTestData
Please make a folder with your name and issue like Russel-MultiSession-Integration-error
and upload there, then let me know when the upload is finished and I will look at it.

Hi @russ-telfer,
I have found the integrator bug which you posted at the start of the topic finally !
It is triggered when you try to integrate OSC CFA (so color data that needs to be demosaiced/debayered) and you have set the Bayer/X-Trans alogrithm in 0) RAWE/FITS to no interpolation which is not the right setting for your purpose probably. Simply set it to Adpative Airy Disc and things should be fine.
I will fix the error as well now, it is caused by this unexpected processing of CFA data without actually debayering it.

Hi @russ-telfer,
Fixed in the next release 2.0.0-beta23:
- FIXED INTEGRATION BAYER DRIZZLE BUG
If OSC data that still needs to be debayered is loaded and the user want to integrate with Bayer Drizzle ,but has set the demosaic algorithm in 0) RAW/FITS to no interpolation, an error was thrown in the Integrator stating an ArrayIndexOutOfBoundsException Index 1 out of bounds for length 1. The no interpolation algorithm is for users with OSC camera's that have the CFA filters removed from the sensor. The algorithm enables them to shoot monochrome narrowband with a camera that was previously a color camera. This exception is now caught properly with the following message:
Hi @russ-telfer,
The issue is fixed, you can try 2.0.0-beta23 which was released today 😉
