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 have been trying out the new Beta release.
I notice that if I load some images and then trigger an action that APP seems to stop processing if I leave the machine for a while. I am sure the previous releases continued to process while I was not present at the system, see the gap in the below log entries between 12:05 and 12:21. I left my lap-top for a while during this period and was expecting it to continue processing.
My lap-top has Intel Core i7-8550U with Intel UHD Graphics 620. The Open GL button now shows green continuously and I think image loading is now a little faster.
Regards
Mike

Yes, the OpenGL issues should be solved in this beta so that's good to hear. Are you on a Macbook? I've noticed this pausing behaviour as well on my old Mac Mini when in screensaver mode.
Hi Vincent,
I am on a Lenovo lap-top running Win 10.  I don't recall seeing this behaviour on earlier releases but with the current beta release it seems to be happening consistently if I leave the lap-top unattended. So far APP has always resumed without issue but it is obviously inconvenient if the lap-top cannot be left unattended while say a large integration is running
Mike
Ofcourse, I have passed this on to Mabula so he can investigate. Thanks for letting us know!
edit: Personally I "solved" it by changing my settings to keep the pc always on when performing such a task. But that's ofcourse only a workaround.
Hi Vincent,
I have also noticed what seems to be a problem with Create Analytical Graph.  I had completed an integration, RGB Combine, Remove LP and Calibrate SC, saved the result as TIFF and looked at the result in Photoshop.
I decided I would look at the subs analysis in graph form and tried graphing using several parameters. The Log File is below. Graphing appeared to start but not graph was displayed.

Thanks for the report! I will pass it on to Mabula to be checked before the next release.
Hi @mestutters & @vincent-mod,
Thank you for sharing this. I have not changed anything with regard to APP pausing for some reason and the java platform with which APP ships is not changed as well.
I have never experienced APP pausing while leaving the computer unattended, so my first impression is that has to do with some Windows settings or even Bios settings for energy magagement?
I must admit, I have not used a screensaver in over 10 years... but I do let the screens turn off quickly when I am gone. Processing always continues I think.
@mestutters, what does windows 10 do when you leave the computer, is a screensaver started or are the screens turned of, or both perhaps?
Anyone else experiencing this issue?
Kind regards,
Mabula
Hi,
I have a similar  issue, for a year that I use APP : when my computer (macbook air) screen turns off, APP is pausing. So I've set the screen to turn of after 3 hours at least.
My APP version is 1.074.1
David
Hi Mabula,
I have been repeating as best as I can recall the processing that I did earlier and I have to say that at present I cannot reproduce the problems I encountered last week. Â
a) I have reprocessed one of my largest integrations and while doing so left my lap-top unattended and during all three observations APP continued processing.
b)Â Â Also I tested the Analytical Graphing feature after each stage of the integration and again sometime after the integration had completed and on each occasion the requested graph has been displayed.
I think I did not do a restart after I upgraded to 1.075 Beta 5 so maybe there was something residual from the earlier release. I have since done a restart and Windows upgrade has also made some changes.
For the avoidance of doubt I should have said the lap-top was in sleep mode rather than screen saver mode.
I will get back if I see any reoccurrence of these issues but at the moment it seems to have been a transient problem.
Regards
Mike
On OSX you can use Caffeine to avoid having the computer getting to sleep: http://lightheadsw.com/caffeine/
This allows you to not have to set the sleep time to something ridiculous the rest of the time you're not using APP. Then you have to NOT FORGET turning it on!
