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, i came across a strange issue in 1.083.02 for MACOS: after Analize Stars has completed, when choosing a reference frame, the buttons for Start Registration, Normalize Lights and Integrate Lights get disabled (light blue letters) with no action upon click Also a new reference cannot be set any more. I cannot remember seeing such behavior in a previous version. It seems the GUI is still active (help texts, selecting frames etc. works fine), just the buttons are dead, so I am stuck. I needed to chance ref frame because the previous Registration failed on all frames (which I also never had seen before)I hesitate to reset the whole program. Is there any way to reset the software one step and get running again? Running MacOs 12.3 on a 27" imac with i7-6700K and 24 MB RAM.
Thanks,
Jochen
@jochen-scharmann Hi Jochen. I just tried myself on macOS 12.3 and APP 1.083.2 and I cannot reproduce the behavior you describe. I am afraid that you may have encountered a glitch in APP. And I am afraid that there is no way to solve this issue other than stopping APP and trying again.
It was strange...
1) I left APP running, with all lights & Calibration masters loaded.
2) I selected the lights again, (unselected few others) and clicked "Integrate" which was available again, APP started with registration again, but failed.
3) I got the message if I would like to try another reference frame, confirmed OK
4) I hit integrate again, APP ran fine through registration, Normalization and Integration ( except for the skipped LNC, see other thread)
Seems I am finally pushing my late 2015 imac to the limit... 🙁
