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.
Astro Pixel Processor 2.0.0-beta25 release notes
Â
- FIXED EXTERNAL OPENGL IMAGE VIEWER WITH DESKTOP SCALING WINDOWS & LINUX
As reported here https://www.astropixelprocessor.com/community/main-forum/cpu-vs-opengl-display-differences/#post-29276 the external OpenGL image viewer was not working correctly in combination with desktop scaling / HiDPI settings on Windows and Linux. This is fixed now. The bug caused the image to be miscentered with not logical zoom in/out response. This was a regresssion bug caused by an external dependency for OpenGL.
- IMPROVED RGB Combine Tool
We have updated all warning messages in the tool to give better instructions on how to solve an issue like incompatible data due to different image dimension, which almost always mean that the data is not yet registered
- FIXED RGB Combine Tool ArrayIndexOutOfBounds bug
We have fixed this bug as reported here : https://www.astropixelprocessor.com/community/windows/bug-report-app-2-0-0-beta22-windows-64bit-encountered-error-in-module-combinethreechannelfloatbufferworker/#post-29081 . It was reported by several users and it was caused by several issues which have all been fixed. It happened especially when processing Dual/Triple/Quad narrowband data where the user had set ForceCFA on in 0)Raw/Fits and/or was trying to combine data that was already processed by a tool like Remove Light Pollution. Data processed with versions prior to 2.0.0-beta25 should now work without this error in the RGB Combine Tool.
- FIXED RGB Combine Tool NegativeArraySize bug
This bug has been solved too https://www.astropixelprocessor.com/community/main-forum/encountered-error-in-module-combinenewbufferedimage-with-16-panel-mosaic/#post-29087 This bug was caused by the composite image becoming larger than the current image size limit in Astro Pixel Processor. If it happens again, the problem is caught and the user is given instructions on how to successfully create the composite within the image size limit
- FIXED FITS image saver CFA tag
Some of the tools like the Batch Crop tool and the Remove Light Pollution had a bug in the fits image saver, causing a CFAIMAGE tag with value "yes" to appear in the saved FITS headers allthough it should have said "no". This bug was also related to the RGB Combine ArrayIndexOutOfBouns bug.
