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.
Hi,
I'm trying APP, so I'm not an expert user and in general I'm not an expert in astroimage processing.
I shot 22 frames of Rosette nebula with my modded Canon EOS550D some weeks ago and tried to integrate them in APP.
Strangely, I found quite a few colored dot cluster in the integration result, red, blue, white, everywhere.
Could you help me to understand what's wrong in my stesps (default settings everywhere, 22 frames of 5 min dithered, biases, flats, dark flats, NO dark)?
Attached you can find the integration result and a detail with circled in white some of the dot clusters.
Thanks,
Alberto
Yes, I get that too sometimes. Not sure why either but I'd like to know.
Verwenden Sie die neueste Version von APP? Wenn ja, aktivieren Sie den automatischen Modus während der Integration. In einer älteren Version muss Manuel die Ausreißer-Ablehnung aktivieren, z. B. Sigma-Clipping oder Mad Sigma. Dann sollten diese Hotpixel-Cluster verschwinden.
Zusätzlich würde ich eine schlechte Pixelkarte empfehlen. 20 Dunkelheiten bei 300s mit geschlossenem Kameradeckel.
Laden Sie dann Lights Darks, Flats und Bias und überprüfen Sie bpm unter Calibration.
Kalibrieren Sie dann die Bilder neu und integrieren Sie sie.
Mit freundlichen Grüßen
V.1.075
I left everything default.
If I understood well, I have to try with the new version (I tried the download, buy It seems very very slow and doesn't complete).
I built a bad pixel map for a previous test, I'll try ti use that (but I'm dire there aren't so many bad pixel in my frames).
Come back with the results.s, thanks.
