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.

Very nice!

Ā 

I just did a 17 hour SHO image hoping to catch the Soap Bubble only to discover I did not have correct camera rotation. Doh!

Ā 

Someone obviously moved the target. That is my story and I am sticking with it. 😉Ā

@jeffmorgan Thanks Jeff!

Well, it's a soap bubble...they dance, pop, and spawn in the ether...

I've done both a SHO and LRGBHOS of the Cresent...but I find that it pops in O-III ...picking up the Wolf-Rayet shock wave and the Soap Bubble really well. I am now working on a LRGBHOO version, the SII doesn't really boost any of the nebulosity at all. I get plenty of signal in Red, but may shoot another set of LRGB adjusting gain...I find the Red tends to blow out easily in this region.Ā Ā
