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.
Hi guys
I'm currently planning to work on multi cameras and optics projects.
The data is like this:
Wide field frames around Alfirk in the Cepheus using 100mm lens and Nikon D810
Some objects in the field of view of the wide filed image:
LDN1235 - 530mm and Nikon D810 (4.88 micron)
Iris nebula - 1120mm and Nikon D810 (4.88 micron)
VDB152 - 612mm and QSI683 LRGB (5.4 micro)

Do you think that it is possible to integrate them together?
I'm quite new to this type of projects.
It will be super helpful if someone can help me to figure out the best work flow for projects like this.

Thank you!

Yes that should be possible. Have a look at this result which is a integration of data of all kinds of users together; this is the kind of setting where APP shines in having best-in class calibration. You will need calibration files for all situations, you can go through the integration and correction process for each scope/sensor, then combine those end-results with each other.

Hi Vincent
Do you usually put all the subs together from the beginning and go through the whole process or integrate each group separately and register/integrate them again separately (similar to mosaic?)?

Thank you!

If your system can handle it you can combine them and it would (I think) create a better result. But memory will be a problem I think, so then I would combine 2 datasets first and combine the results later.

Thank you Vincent.
