Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.

It did take a long time to have the work finished on this and it  will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...

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) 😉
