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'm about to create a new workstation to accelerate my workflows and was wondering if anybody had experience with a system based on the new AMD 3960x or 3970x processors.
Given the tests it looks like this could be a game changer, especially if combined with an M2. NVME Disk that , given the implementation of the PCIe 4.0 spec , would allow insane disk transfer times, unknown until now.
As building such a system is nearly twice the cost of an Intel system I'd really love to hear back from anybody who can tell me it APP would benefit from this. Thanks
Yes, Mabula (the developer of APP) uses a threadripper system. It indeed is very well suited for a program like APP, cores are fully used where possible by our code. SSD disk helps a lot as well and a lot of memory. So yes, if you have the possibility to get such a system, go for it.
Thanks that makes my choice easy then.
So I follwed your guidance and for anyone interested I can confirm that APP runs nicely on a new Threadripper 3970 system, uses the cores superb:
Calculation time in APP went down from above 4hrs to 6 minutes. Old system : Core I7 8770k, 32GB Ram , 1TB NVME PCIE3 disks, Nvidia GTX1080Ti, New System: AMD Threadripper3970x, 128GBRam, several 1TB and 2TB NVME M2 PCIE4 disks, NVIDIA 1080Ti
Wow, that's quite the beast there. 🙂 Nice!
Wow! Looks like it's worth it
