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.

 

Need some input on how to handle noise (get a cleaner picture)

I'm doing some processing of M16 and I have some god awful noise in the picture, which is something i have noticed at more than one target, so i must be doing something wrong.

I am dithering, shooting at -10 with my zwo533 and in this picture i have 50 subs. And I have darks and all.
It is also sessions from 2 different nights. Night 1 in session 1, night 2 in session 2. All shot with the L-extreme.

Yes, unfortunately noise will always be part of the game. The only way to get rid of that nicely (and even then it won't be gone) is to have a lot of data and long exposures. What's your exposure time here?

Other than that, noise reduction tools would help, APP is going to have that in the future as well, but personally I almost never use it. I just accepted it and removing it usually hurts details.

I think I found the sinner, I didn't check me subs so like 60% of them was crap. This is the final result. Subs were 180s

Mm, contrast on this one is much higher than the first picture, so I wonder if it's really gone in the background?
