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.
Please excuse me immediately, but I downloaded the sw. I followed the tutorial for the first procedures, but I still see the image in black and white and I can't find where to add all the images and then how can I transform the bayer image into color?
Thanks...
It's simple... before ''1)LOAD'' you check on ''0)RAW/FIT'' and MAKE-CHECK ''force Bayer CFA''.
Thanks Stojang, I did it. I think APP is great for preparing the final file. I do not find how to export the file, as well as in FIT and (I finish) the palettes of steps go from 6 to 9 ... and 7 and 8?!? Or rightly so (I use it with Apple).
When step 6 finishes a new file is created on disk and it will show up at the bottom of the file list. Double click it to open it in the viewer. Then click the Save button in the upper right of APP and you'll get a few popups that allow you to specify the file name and the output format.
Please note that APP generates images with a linear histogram. When you export those images and open them in an external viewer, the images very likely will be (almost) completely black. The histogram needs to be stretched first and this can be achieved by ticking the Stretch check box to the left of the Save button.
HTH, Wouter
Good!!! There are almost ... when (to which passage) and where can I ask the sw to eliminate the noise and make the background more homogeneous? After this I promise that for today I don't bother anymore. Thanks
