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 Mabula/all
Downloaded Beta 7 yesterday, all worked well apart from trying to mosaic two stacked panels. I enabled same camera/optics, tried with and without dynamic distortion correction, MBB set to 8 % but still getting this weird circular distortion (Black hole like 😉 ) in the centre of each pane. its not on the individual stacked panes so it is something being done in the mosaic integration. Any ideas ???
I had some great success creating such vortexes, almost reminding me of calabi-yau like manifolds ...
I varied paramters in 4, register, pattern, triangles or pentagons maybe?, scale start and stop, calibrated projej, equitangular, also with changing reference frames. thenm it worked (with a bigger mosaik, also an option).
it was strange and I did not know why it worked in the end.
Hi,
Have you tried without enabling same camera/optics ?
David
Thank you David, yes I tried it this morning and it did indeed fix it 😊. No idea why though as it was data taken with same optics and even same session, I’ve never disabled this before 🤷♂️
Russ
Great!
For mosaic registration, same camera/optics have to be unchecked. But for regular frame integration it's better to enable it.
David
@russ-telfer Yes, for mosaics the same camera/optics has to be switched off. This is a bit of a technical view of "camera" as basically a mosaic is having a different Field Of View etc then a regular image.
