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.
Hi, I took more data on NA nebula. Oiii and sii.
I loaded all frames from Ha panel one into hydrogen alpha, and l frames from Ha panel 2 under custom and typed in hydrogen alpha-2, same with other 2 channels.
Loaded darks, flats and dark flats and hit normalize.
Many frames didn't register... some were panel 1 and some panel 2, so not sure what went wrong....should I load all Ha into Ha even if they are 2 panels?
I assumed I had to register all frames together...regardless of 2 panels.
Please help!

Hi Adam @singding,
No, you need to load all H-alpha frames of all panels as H-alpha. You shouldn't assign a different channel name for H-alpha of another panel. It's all H-alpha 😉
So you are trying to make a multi-channel mosaic right?
What settings did you use in 3) and 4) ? And how many stars were detected in your frames?
For a mosaic registration you need a bit different settings than the defaults, so let me know what settings you used and then I can give you some pointers.
Cheers,

So it's a 2 channel "mosaic" or integration with 10% overlap. Ha oui, and sii.
So I shouldn't make each channel and each panel a separate integration then and then integrate the panels after?
I tried the recommended settings, lowered kappa all the way, upped the start and stop?
I apologize I can't access the computer now, but I did try a few settings.
When I did my hargb, I did each panel separate, then combined them after....
Hope this helps for now. Basically registration failed for many frames that appeared ok..500 to 800 stars I think
Adam
