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.
Good evening, like everyone I am doing 3 exposures with different times for the orion nebula.
Can the files all be put together? Using the option for different nights?
Or can the 3 separate sets be processed, putting a single reference frame to align the stars?
Thanks 🙂

You can combine all the data, even from different camera's and telescopes, so this is certainly possible. However, your aim is a HDR integration I think. This is not yet a capability in APP.
I would like to elaborate the 3 sets and then maybe blend them with photoshop.
But use a single reference frame for the stars.
Ah got it, so you can select a manual reference frame by going to tab 3 and analyze the stars. Then to tab 4 and clicking on "manual reference" on top, followed by selecting the frame in the list below to be the reference.
But can I use the 300s exposure for all sets for reference? Even from 10s and 120s?
You should be able to yes, if you load all sessions in and manually select that reference.
I would like to make all 3 exposures have the same alignment for photoshop.
Yes, so what you also can do is to make each set separately first, then load in the integrations again as lights, going to tab 4, click register and after that down in tab 4, save registered frames. If you want to save them as jpeg or tiff, you can reload a registered integration and press "save" on the right to export it as such a format.
But loading them in as different sessions will also make it possible to get 3 integrations that are registered to each other.
Thx 🙂
