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.
Dear Mabula,
today I tried to do comet processing using APP version 2.0.0 beta 13 and got a java.lang.NullPointerException while pointing the comet during the registration process:
It happened twice around or perhaps even at the same image while clicking at the comet. I could not see which image it was. I had the image viewer full screen (1280 x 1048). Then I repeated the registration another time with the image viewer i partial view (approximately 800 x 600px) and the process continued happily.
Not sure if the above makes sense and is of some use, happy to do some further testing if needed.

The past few days I have been processing several cometary recordings and found that, even at reduced window size, the above error pops up every now and then. In the end I get everything processed, but it takes a lot more time as a result of it, while at times it is hard or even impossible to get through the registration process.
Nicolàs
Last update: I now have a set of 197 comet-subs that constantly fails to register using APP 2.0.0 beta 13, each time at a different sub, but mostly either at the first (sub #1) or the second occasion (sub #10), so I switched back to APP 1.083 and successfully stacked the data there.
I can provide access to my processing computer to Mabula if that is helpful (we did that before).
Nicolàs
Ok, very interesting. Mabula is going to work on the comet feature, so would you mind uploading a subset of comet lights and calibration files to our server?
Hi Vincent,
thanks for your response, I have uploaded 20 lights to InFINNity-Deck-cometRegisterFailure and four masters in a subfolder of that.
Please let me know if you need more lights.
Nicolàs
Thanks Nicolas, I've informed Mabula.
Hi Nicolàs @infinnity-deck,
I am working on the comet processing at the moment and I was looking at your issue. With 2.0.0-beta17 I can not reproduce your issue whatever I try with selecting the comet nucleus.
Can you test with beta17 on your data and let me know if this issue still occurs or not?
Mabula
Dear Mabula,
thanks for your new beta-version! Just now I tested it successfully on that dataset, no more nullpointer exceptions, so all is good.
kind regards,
Nicolàs
Thank you @infinnity-deck for your confirmation!
The next release 2.0.0-beta18 will have many improvements for comet processing, we are close to releasing it as well 😉

I'm having a similar issue when I try to register my comet images.
I use many subs (600-1000x5 seconds) with my goto Dob and have been able to do comet registration before in APP but this time I'm stumped.
I've searched the subs for a bad frame but I keep getting this message:
Encountered error in module:
RegistrationActionListener
Error message:
java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "<local7>" is null
Cause:
Cannot invoke "String.equals(Object)" because "<local7>" is null
ox.h(FrameListJTable.java:445)
ox.e(FrameListJTable.java:356)
uT.a(RegistrationActionListener.java:1155)
uT.doInBackground(RegistrationActionListener.java:977)
and it fails.
Any thoughts?
Currently on beta29 and I also get a null pointer when skipping an image during comet registration:
Encountered error in module:
RegistrationActionListener
Error message:
java.lang.NullPointerException: Cannot invoke "pF.execute()" because "<local15>[<local59>]" is null
Cause:
Cannot invoke "pF.execute()" because "<local15>[<local59>]" is null

uT.doInBackground(RegistrationActionListener.java:977)
java.desktop/javax.swing.SwingWorker$1.call(Unknown Source)
java.base/java.util.concurrent.FutureTask.run(Unknown Source)
Also the image is completely skewed:
This doesn't happen if I place the pointer on the comet before skipping the image.
I have two different series of comet data I have converted to TIFFs in order to remove the stars before stacking. Upon loading the TIFFs I get this error when attempting to register. It won't even allow me to get to the first frame where I ID the comet center. The NullPointerException happens with both sets of data. Beta 2.0 ver 38
