Apr 29 2026 APP 2.0.0-beta42 has been released !
New improved Normalization engine, Fixed random crashes in integration, fixed RGB Combine & Calibrate Star Colors, fixed Narrowband extraction algorithms, new development platform with performance gains, bug fixes in the tools, etc...

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 made a mistake in giving a name for a new distortion model. Can I change that name and if so, where do I find the file containing that new name when searching under Windows Explorer?
Thank you for your answer and best regards,
Thierry
I have to say I never used a distortion model myself. It isn't stored in the working directory that you set for APP?
@vincent-mod
I have been searching within the directory C:\Users\...\AppData\Local\ AstroPixelProcessor but couldn’t find any file that has the date stamp corresponding to the date I added the new distortion model.
I’d like to delete one old distortion model as well in the file I’m looking for.
Any other suggestion where to look at?
Is that your work directory? APP asks what directory you want to use for data processing at the start.
@vincent-mod
I have been searching in the working directory first but couldn’t find it there, therefore I have been searching in the installation directory of APP which is the one I mentioned in my earlier post.
Any other idea where to look for?
@vincent-mod
I meanwhile found the file: it sits directly under C:\Users\me as user\ under the name “APP-cameraProfiles.txt”
Oh hey, that is weird. I'll pass this on to Mabula!
@vincent-mod
I modified the file meanwhile: I deleted 1 distortion model within the file and modified the name of the other distortion model. When looking in APP it looks fine.
Ok, got word from Mabula. So the location of the profile is indeed correct, the thing is that a profile isn't dependent on a dataset or project so the profile is stored in the location of the license. It should be used carefully as well, especially when using telescope equipment. A profile works best when you have a regular camera with objective as this doesn't change. A Newtonian telescope for example, there the profile will change depending on things like collimation. It can be used to speed up mosaics for instance, but only when you can be sure of the profile staying exactly the same, so in general the advice is not to use it with telescope data.
@vincent-mod
Thank you for the extra information. It seems indeed logic that a profile for a telescope is less predictable then for a camera with lens. I will see what I will do with one profile, which is a ZWO camera on my Celestron 9.25”.
Best regards,
Thierry
