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.
Could you please allow to select multiple lights in teh analytical results plot, i meant with a click and displacement to select multiple lights to for example remove them?
That would indeed be a great addition - I often find myself having to delete large numbers of subs if, for example, clouds come in for a period. It is painstakingly slow doing it one by one...
If you are trying to sort say on quality, click on the quality heading in file list and it will sort best to worst or worst to best, then you can select a range of worst files in the list and remove or delete them at once. WARNING! A couple of times I tried deleting and it deleted the whole fileset, including my calibration files and there was no recovery - I just spent a whole day redoing my calibration frames as this just happened to me using (beta39) This is something @mabula-admin needs to address. So make sure you have backups of both your session and your calibration frames. What I do for historical reference, I put my calibration masters in a folder in my session folder , then I use that copy for processing. Plus I have a backup of my lights. Safest to use remove from file list.
Another viable option would be after star analysis, with the hit of one button, one could get rid of the failed frames, or the same with the missing registration frames...that would allow speeding up the proccess. PleaseÂ
Thank you. That's why I'm in love with APP
Hi Hector @hcdv,
That is great to hear :-), the issue is on our list and we will address it probably after the 2.0.0 stable release together with the publication of the full manual.
