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.
On trying to integrate my result is nothing but a bluegreen mess. I also get the attached error. I have tried a couple different times and I get the same result.
My subs all look okay. I did have to run them through XnConvert to bring them from the native .dng to tif files. Camera is a Pentax K3, subs are 60x 180s, 30 bias, 10 flat, 25 darks. I went ahead and bought the owners license because on heavy star fields DSS fails, and PI duplicates your files over and over again, plus I wanted the background neutralization that APP has.

Hi @imnewhere,
I do see at least 1 sub in the list having some failure during integration. In these cases it's always best to share the data so I can take a closer look. If you want you can upload like 10 lights, 10 bias, 10 darks, 10 flats to the appserver: appserver and log-in with username and password: appuser
Please create a folder with your name on it first. Thank you!
I don't think converting to tif is a solution. I tried it and the colours are flat. But I believe the main problem is that the tif has been colour converted by the raw-to-colour process, so the tif is not a true raw file that can be properly calibrated. (unless you can convert to tif without colour conversion.)
Yes, conversions are never advised (which is why dng support is so important for these cases) as they depend completely on the converter, many times converters change the data which isn't what you want. But, let's see the subs first and see if there's indeed a problem with the tifs.
