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 am trying out APP before making a decision about buying. Last night I loaded about 60 light , 60 bias, 45 dark and 32 flat frames. On 'Calibrate' application hangs. I re-tried three times but hangs at same step every time: 'integrate bias frames:integrating pixels 1 to 4507 of 42560000'.
Not sure what is different about this batch but the one before it with 30 frames in each category worked fine.
All files are .ARW(Sony RX1RII) files. APP is running on MacOS 11.1. I have allocated 6GB RAM to APP and have way more than enough disk space.

Any suggestions about how to proceed further?
Hi and thanks for trying APP, this is exactly why we have a trial. 🙂
So, this is a crash I've not seen before as far as I can remember. Could you try to integrate without calibration files?

You mean skip Calibrate step but do use flats,bias and darks in subsequent steps?
Â
No, just load in the lights and no calibration data, go to tab 6 and press "integrate". 🙂 I'm wondering if there is an issue with the calibration data.

That worked. I did two sessions last night back to back with no delay in between. Images from first session are processed end to end just fine.
Difference between the two sessions is that in first one shutter was open for 20 seconds whereas in second it was for 25 seconds. Second difference first session was 30 shots (lights, flats , darks and bias) and second was 60 lights and bias, between 30-40 flats and darks. Other than that camera was pointed in same direction for both sessions.
What could be the reason for second batch of images not working?
Â
Â
Excellent! So, what the actual reason is I'm not sure. But it does point to an issue with something in the calibration data. Good thing to do now would be to add calibration data and see when it starts to fail. Often, failures arise when using darks with an issue. So my advice would be to try to do this again, using bias and flats only.
In the right hand panel (don't know what it is called) is there a way to reset the default values after making changes to defaults? For example in LRÂ double clicking on the slider resets the values back.
I don't think so no, just a reset button for 1 slider. But definitely something that will be possible in a future version.

Btw, I don't think that reset button works either.

The reset button resets the G slider.
