Colored noise lines...

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.

Hi,

 

I have been using APP with great succes for a couple of months until I started to notice these pretty bright lines of noise in my images. I made these go away with creating a new BPM with a kappa high of 2.0. Now I have a different problem. I have these colored noise lines showing around the stars. Think I tried all possible combinations of stacking to get rid of them and getting a bit desperate about it:P

example in screenshot below. Can anybody help me with these?

Ok so I used my old BPM and the star artefact problem is exchanged for the (hot) noise lines again. Wierd thing is I never had this noise before last week with the same calibration frames.
