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.
Currently after an imaging run I process the subs through Analyze Stars (Tab 3) and evaluate subs based on star roundness. Anything under .60 gets deleted. When I feel enough integration time has been reached, I process everything with no further screening of subs.
I am wondering about the correctness of this. Is there a function like PI’s SubFrameSelector? What other tools, methods, and guidelines are APP users employing?
Usually you won't really need to delete data based on that, if you have enough. APP will apply a quality rating to each sub and will use the worse frames less for the end-result, but it may still help quite a bit to increase overall signal.
Hi Vincent, does this mean that very bad subs will be skipped by APP? So, I don't have to worry about bad subs?
They won't be skipped no, but they will have less of an impact. If you have subs with clouds or something, those I would take out manually. They can be skipped if you select to stack the "top-90%" or whatever percentage you want in the integrate tab.
Vincent, thanks for the reply.

Hi Jeff @jeffmorgan,
Please try APP 2.0.0-beta17 from our downloads page if you have not tried it yet. It shows you analytical graphs will processing, you can sort the data by clicking on the column headers and then if you plot the data on for isntance the star shape then you can easily remove frames with bad stars :-), you can make different plots with the right mouse button click menu on the frame list.
