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.
I need to adjust the hard disk configuration as I keep getting 'not enough disk space' error message, and need to increase the space available. All my disk have many GBs of space.Â
To the immediate right of the CFG button there is a grren HDD 119GB
When I hover over the CFG button, it says this button is used to: a. adjust the amount of RAM memory available to APP and b: enable/disable ToolTips
However when clicked on there is no mention of RAM, etc.
Obviously I am doing something wrong but cannot work out what that is.
Please advise

RAM and diskspace are separate things. If you dont have enough freed HD space, then either free up space, buy a bigger SSD drive or split the stack into two, or dont drizzle.
I once had a need to 2TB of free HD space for stacking and that wasnt even a mosaic.

Hi Frank, @thedwo
Thank you very much for your question. I understand from your question that you are using an old APP version still. Please update to the latest version 2.0.0-beta36 by going to our Downloads page at the top of the website and simply download the latest release at any time. The CFG menu is no longer there, we know have a new menu LICENSE & SETTINGS.
It is also like Stefan indicates, you will need to make room on your hard disk if the integration needs more space.

@digitaliz-se Just to make sure I'm understanding correctly, splitting the stacks is essentially:
Stack 5x 200 file batches instead of a single 1000 file batch
Stack the resulting 5 files together.
So basically, stack the stacks?
Â
Yes!
you can either make separate sessions or do sessions in APP. The stack the stacks.

@digitaliz-se That's awesome. I have 12 to 24 hours of integration time on some things (with 10s frames, that's a lot of files) with my little Seestar S50. This will certainly save me a few headaches.
