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.
I have two different focal length subs and would like to combine them and make RGBHOO.Â
1. Ha and OIII using mono camera at 1000mm focal length.
2. OSC with L-Ultimate at 460mm focal length
3. OSC with L-Ultimate at 360mm focal length
What is the best way to combine these?Â
I have tried putting them all together with their respective calibration frames in APP and it works to some extent using RGBHOO but I'm not able to use Ha and OIII from L Ultimate.Â
Â
Any suggestions are greatly appreciated.

 after stacking them all together. I would like to add Ha and O from L ultimate into this.
Split your OSC files into RGB (still should do this even using l-enhance, just green will be more dim), then stack those results into master R, G, and B files. Stack your Ha and Oiii into master lights as well. Once you finish that take your master R, G, B, Ha, and Oiii files and put them back in as lights again, then run them with advanced on the Normalization tab, and I'd run 4th degree and 5 iterations on local normalization correction on the integrate tab, but leave MBB unchecked. Make sure to uncheck same camera and optics on the registration tab. You probably will not need to do it as a mosaic, but if you still have any problems you may give that a shot.
