June 24 2026 APP 2.0.0-beta46 has been released !

Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.

May 27 2026 APP 2.0.0-beta45 has been released !

Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

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.

Encountered error in module:
SixteenBitsFitsConverter

Error message:
java.lang.NullPointerException: Cannot load from object array because "this.a" is null

Cause:
Cannot load from object array because "this.a" is null
nF.a(Unknown Source)
nF.doInBackground(Unknown Source)
java.desktop/javax.swing.SwingWorker$1.call(Unknown Source)
java.base/java.util.concurrent.FutureTask.run(Unknown Source)

 

It is apparently important enough to stop everything during stacking....

 

I have 6 hours of data over 2 nights of imaging and I cannot stack it.   I have never seen this error before.

Apologies for the delay. Did this get solved or are you still not able to process?

I tracked it down to APP not being able to stack files on my portable USB3 SSD drive.   Regular USB3 portable drives work fine.

Hi @tempusfugitxxii,

Does the issue occur as well with 2.0.0-beta26? Can you check and let me know? It looks like a bug that was fixed actually.

Hi @tempusfugitxxii,

Can you share more information, at what stage does the error occur? I have never seen this one myself yet...

Also, in beta26 the error message should be a bit more informative as the one you showed at the start of this topic, can you share the error message from beta26?

Maybe you can also upload your data and tell me which settings you use so this error pops-ups?

Please make a folder name like:  Tempus-SixteenBitsFitsConverter-bug

and let me know once uploaded, thanks !

Mabula
