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 itĀ 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.
Is there a way to process lights only?
Thanks
Of course, just don't add calibration frames. I often only do lights. With a good sensor, good optics, you can often get by without calibration.
Like @astrogee says, yes totally possible. For a really nice result you would need a near perfect sensor for not using any calibration though, even the most expensive ones do have some amp-glow and such. And you'd need perfect illumination as well without any dust to get away from flats. It's possible, but usually very expensive. And I think using bias will enable you to stretch more.
@vincent-modĀ Thanks for your replies.Ā Some nights at the end of a session, I want to take a quick look at a target, but not do a full blown session.Ā Just take a handful of lights and process those.Ā Did not know if APP would do that or not.Ā I just got the trial last night.

I used a modded Pentax K-5II to start, and didn't really know what amp glow was that people were referring to. No bias issues either. Then I bought an ASI294 Pro-cooled - talk about amp glow! Now I have to do darks for sure. The Pentax K-5II sensor (by Sony) is probably one of the best. ZWO now puts it in the ASI071 - $2000 astrocam. I loved it but I could not control the Pentax so I gave it up for an astrocam 😢 Ā
