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.

My astro-buddy and I braved the -30 Celsius wind chill temperature last night near Ottawa Canada and spent 5 hours under on the best and most pristine skies we've ever seen. The was no Moon and not a cloud in the sky... it was simply perfect for astrophotography. Here  is my first Great Orion and Running Man Nebulae shot in a year and I hope it won't be the last because the weather has been so poor.

I feel that APP did a great job on this image considering it was all very short 30-second subs.  Hello Mabula, it has been a long time since you have heard from me. I hope you are well and that the work is progressing).

That's awesome. I see a pillar feature I had not seen before. Nice capture!

Great image @rudypohlgmail-com !

There sure is a lot of signal present in your data, awesome 😉

I know this area is just full of colder and brown dust which can make it pretty hard to correct the data for gradients. I think you did an excellent job though Rudy. Great and lots of color as well.

All is well Rudy, thank you for asking. I am working hard on several improvements for APP 1.057 like strongly improved outlier rejection filters. I will soon introduce a new outlier rejection filter ;-), it will be an improved version of Linear Fit Clipping, it will work better and faster so I think this will be a very nice feature.

Your proposed improvements on color stretching will come as well soon 😉

Cheers,

Mabula
