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.

When stacking a mosaic if I let the app use the highest Quality Score image as the reference frame the registration in part of the image is bad.  If I instead tell it to use the lowest Quality Score image the registration is fine (although the color is off).  I have several panels I am combining so I was able to try different combinations and the results were the same.  Changing the reference frame changes the ability to register.  Is this expected behavior?

I batch cropped the 2 results:

M42 v2 13 14 23 24 high crop St
M42 v2 13 14 23 24 low crop St

Hi Steven, @mrrat

That is not expected behaviour, the reference chosen does determing hope APP will calculate the mosaic. In this case I would suspect that the calculation is slightly more difficult somehow. Maybe a tweak of the registration parameters will solve it, or increase the number of stars a little bit in 3) 😉
