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,
Being a "user" of APP for less than 24 hours I have it my second snag. My first is my lack of ability which I live with. The second is that using MacOS Monterey, I see my HD files but external discs show no files at all.
What am I not doing or doing wrong? It would be helpful for me to access my data to put APP through its paces.
Â
Also even after a few hours of trying fathom out how it works and read a considerable amount of the forum I am seriously impressed and greatly encouraged by the program and especially the wealth of support given to members. Although I am still on trial I feel it inevitable that I will be fully signed up for the long haul before long.
Â
cheers

It works fine with external drives but Java just doesn't show other drives in a MacOS standard way. What you're looking for is in /Volumes on the Mac (you'll have to use the UNIX path names as that is what it is under the surface). In the open or save dialog, just type /volumes and enter and it'll show you the list of drives. Or you can click the dropdown selection at the top and select / and then you'll see volumes listed. Then double-click the volumes line to see your external drives.
Thank you for the prompt response.
I clearly do not express myself well.
I see the Volumes (all the external discs ) and can select all of them but when selected there are no files or folders listed.Â

Hi,
Apologies all round.
I found a tag in OS Â that as for permission to be granted to APP.

Crisis averted.
Many thanks and apologies for lack of knowledge.
No need for an apology, this is always how we learn!
