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.
Hello, i'm really new with APP, i have already success some stacks but i have fiew issues and questions. I hope you can share your knowlege and experience to solve my issues.
First of all, for the moment i live in Antarctica, so i have a bit of "light pollution" with southern lights, i think the stack may be a bit challenging. But i'm impressed by APP and his features, the stack is well control and the quality is good. (Better than Astap and DSS)
Because of southern lights and beautifull landscape, i like to shoot 360° panorama with a 40mm. This year i will try to improve my workflow, that's why i bought APP.
So there is my questions :
1°) In case of multisessions, sometimes i have a bit of foreground and for now i just crop it, but do we have the opportunity to mask it directly in APP like with a brush or something ?
2°) In my panoramas i have like 45 to 60 stacks to do, it's a long way... I tried DSS in the past, with stack by lots, it was awesome, once the process is started i just leave to come back fiew hours later and it's all done. Does APP have a hidden feature to stack by groups like DSS ?
3°) I was using PTGUI to stich all my panels wich is great, he allowed me to do really large mosaics. I bought APP specially for mosaics, because he's really good to stitch panels togethers with LNC and MBB even with different lenses.
But, like on this old topic "https://www.astropixelprocessor.com/community/main-forum/large-mosaics/", i have the same issue due to size limit :(. Is the limit still there or i missed something ? 😰
4°) Can we do a rejection on the mosaic to remove only airglow / aurora ? This could be usefull to work in a separate way the background with the milkyway, and to blend back airglow/aurora if needed. (Like a starless technique)
5°) For now, i use the mosaic tutorials of Mabula, they are really helpfull and great. Does the workflow in thoses tutorials is the same in 2024 ?
6°) There is a way to keep the settings when i save in TIFF ? Like to keep 32 bits + 300 DPI (for very large print)
Thank you for your help and advice !
Sorry my english isn't really great 🙁
