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.
I'm having a bit of trouble analyzing an image with Astrometry.net because of improper DEC and RA coordinates after a crop.
When you (batch) crop an image in the Tools tab, it doesn't look like the DEC and RA coordinates in the header are updated to reflect the new center of the cropped image.
Shouldn't the reference point (CRVAL1 and CRVAL2) for the new center (and potentially other WCS-related keywords) be recalculated to ensure the mapping remains correct?

Hi Gilles @museceleste,
Thank you very much for your post.
APP 2.0.0-beta33 had the improvement that at least from now on, relevant and distinct FITS tags will remain present in the FITS files that APP produces. So if you do not crop the files, the DEC and RA coordinates and other pointing information from the reference are stored in the integration files.
Unfortunately, APP does not plate solve yet, so we can not update the coordinates/pointing information yet. I will try to implement this soon going forward.Â
For now, you will need to plate solve the image in the software that requires it. Can't Astrometry.net solve this easily by the way?Â

Hello Mabula,
That’s good news, thank you. It represents a fair amount of work but should benefit and bolster the entire product! Curious to know how you are planning it: some packages involve downloading a star database (e.g. Kstar), others will link to Simbad online, etc.
I found the problem by regression. The first time I uploaded to Astrometry, it asked me if I wanted to plate solve the image. Surprised, I then realized that, following a batch crop in APP, the DEC and RA coordinates were gone. But Astrometry will plate solve from the stars all right.

Hi Gilles @museceleste,
You are most welcome, I need to investigate a bit on how to implement it, but it should not be a problem and it is high on my todo list.
Glad all is fine now đŸ˜‰
