Apr 9 2026 APP 2.0.0-beta40 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! 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. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...
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.
Firstly, just want to congratulate the team behind APP for developing an excellent tool. It has simplified my pre-processing immensely, and I don't use any other programs for pre-processing DSOs now. I have a couple of suggestions which I think have already been made, but just to re-iterate:
1. Previously, integrated files had naming conventions which would detail every area e.g. exposure time, binning, LNC, MBB etc. This seems to have been removed. There should be an option in settings to enable it so that people can choose if they want the naming convention to be kept. I personally found it very useful.
2. There should be an option to save a set of parameters starting from star analysis to integration as a file so that it can be loaded when required. For example, I use a particular set of parameters for regular integrations versus mosaics. If each of these settings could be saved as a file which can then be loaded, it would save time.
3. Automatic rejection of frames which cannot be registered/star analysed and proceeding to the normalisation/integration process without aborting the whole process would be good.
Again, thank you to the APP team on their hard work!
Thank for the suggestions!
1) This information is now in the header file, but indeed when the settings is a possibility this might be a good thing to support.
2) Yes, this is on our list to do, I don't have a way to see the roadmap though
3) Agreed, that may be nice indeed. I think things like this will get implemented as we want to automate quite a few steps while retaining the best quality where possible
