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,
Quick question:
For sorting in Frame list panel, what is the difference between "sort frames best to worst" and "sort on quality"?
The latter seems to be sorting by quality score, but "best to worst" seems to yield a different result unrelated to quality score
Good question, never used that option tbh. 🙂 I've asked Mabula for some clarification.
Ah right, so I didn't understand your question well here. 🙂 The sort frames "best to worst" is a switch basically. So when you select that, it switches to "worst to best" and then you select "sort on quality" for instance, depending on the top option in that menu, you will see the highest quality first or the lowest first. And this is the same for all sort options in that menu.
I think it’s on the future enhancement list to allow for clickable column headers to control sort and sort direction, right?
It also appears to sort by sessions as a sub-group.
It would be nice to control which columns get displayed (I don’t use them all).
I also re-arrange the column order, but if I delete subs from the list the screen redraws in the default order. It would also be nice to see user-defined column order (and width) preserved.
Yes, and really helpful would be to be able saving the column order/ column size / column arrangement with CFG, so the frame list is configurable
Is there a way of using only (say) the best 90% of images?
