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.
Trying my third mosaic when i want to combine RGB, APP stops because Java stops. i tried over 5 times. The subs are 736Mb, those of LMC were over 1Gb and did well.
Please can anyone help me?
i tried the same on my MacBookAir and got this message:
I'll let Mabula know, what APP version are you using?
this should be the newest i guess?
It is for now yes
Hi Arie @ary-slingerland,
You are running out of memory unfortunately when you try to combine the data with the RGB Combine tool, right?
It should help for now, if you reduce the actual integrations when you create them by setting the scale factor in 6) integrate to a lower value than 1.0. For instance, try 0,8 and see if you can create the LRGB mosaic then 😉
It is on our todo to make APP more efficient in terms of memory usage for big images like this, so improvements will come.
Mabula
