2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
wouldt be nice because of the small picture window.

Thanks for the suggestion, we'll be looking at such options in a later version.
Beta2: will work in a multiple screen setup,
Thanks !!

It sorta works..you can stretch the whole app accross 2 screens, but it would be spiffy if you could put the display sction in anotor..like "loupe" setting in LR.
Hi Robert @bhill,
Please click on the top left CFG button, this is the configuration menu. Then select to use the image viewer in a separate window and click on save. This second window can by used to only see image data on a 2nd (or 3rd) monitor.
So there is no need to stretch the app accross multiple monitors like you indicate. Let me know if this helps. Please see the below screenshots, where the image viewer is actually on a 2nd and bigger monitor when compared to the primary monitor.

Thanks for that. If only your company would put out a user reference giude. I see many videos out there, If there was a reference one could use in the field....
@bhill, a manual is in the making and it will be released online in HTML and offline in PDF format when APP 2.0 stable will be released 😉
We have also started the official Astro Pixel Processor YouTube channel where we will start posting new official video Tutorials for APP and release announcements with explanation of the new things in each release.

We aim to provide more guidance going forward as you indicate.

@bhill Hi Robert, FWIW here is a workflow I have put together. Â It's not perfect by any standard but it is a reference that helps me remember various processing options and certain available operations and functions in APP.
