Jan 31 2026: APP 2.0.0-beta40 will soon be released with many fixes especially for Linux, upgraded development platform and 10-20% performance boost !
Jan 15 2026: FIXED LICENSE SERVER VPN Tunnel issue
 The issue could have prevented APP to start when using a VPN tunnel or another complicated network configuration, like using APP on a remote computer on a different continent. This issue is fixed now and APP should start normally.
Jan 04 2026: 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. Unfortunately, Mabula was struck by a severe flu virus in the past couple of weeks and thus could not work. He is getting much better now and he has resumed work to release 2.0.0 as soon as possible. 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.
Nov 28 2025:Â APP 2.0.0-beta39 has been released !
I am receiving lots of different error messages and I'm kinda done. I'll start posting these messages here.Â
APP used to automatically downscale and image that was too large. Now, apparently it does not.Â
So, for my multipanel mosaics, apparently I can no longer use APP, unless there is a work around.
Hi @sj_chavez,
Thank you very much for posting your issue here. First of all, I am implementing a lot of improvements for mosaics for the next version 2.0.0-beta39, please check the release notes: https://www.astropixelprocessor.com/community/release-information/astro-pixel-processor-2-0-0-beta39-release-notes-work-in-progress/#post-33139
The error that you have is a downscale of a factor of 0.0x. That means that the result has become infinite, so something really goes wrong with registering your data here. That is very clear. I also see that your star counts are very high. Using high star counts can actually create issues. It is safer and more stable to use 1000-2500 stars and try again if you haven't done so already.
If you are making a wide field mosaic with a very large field of view, you must use calibrated projective model. Is this the case?
Since I am working full-time at the moment on improving the mosaics, it is great time for uploading your data to our server, so I can test it and make sure it works in the next APP 2.0.0-beta39.
Can you upload the dataset on which this happens here:
https://upload.astropixelprocessor.com/
username: uploadData
password: uploadTestData
Please make a folder with your name and issue like: sjChavez-mosaic-errors
and upload your data there and let me know once done, thanks !
Mabula
