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 am using APP on an Ubuntu VM (Proxmox bare-metal host). I am being asked every time to enter my license info.. See my current 3 licenses on the same machine (The RAM varies depending on how much RAM I need in my VM environment and it varies depending on my other VMs).
How can this be fixed? Thanks!

Hi @antoine,
Our security in machine recognition for license security works with the amount of RAM used. So if you keep changing RAM for the VM, you will need to re-activate the license for sure. I can not change that easily. The amount of RAM that you are using is very high as well. Simply set it it fixed for the APP VM on 64 GB or 32GB ?
APP was definitely not designed to run on Virtual Machines because it already runs on Windows, Linux and MacOS which are usually the host of a virtual machine. And I would advise against running it in a virtual machine because performance will always be less than running it direcly on a host.

Hi Mabula! Great to hear from you again. Congrats on pushing the latest updates.
I fixed the issue by removing the "ballooning" memory settings in my VM host to grew depending on the VMs RAM usage. All good now after a restart, the RAM licensing issue is fixed.Â
Just for your education 🙂 This VM system is not a regular VM application like you are used to have on your computer for emulation. It is a "bare metal" virtualization platform like the ones used on Amazon/Google servers and gives 98-99% of RAW performance to the VMs... Coupled with a 64 cores 256GB Ram Server and 100TB NAS for high volume astro-imaging generating 10GB data every night, It gives me and my team full remote access to both Linux VM and Windows VM as each have its pros and cons for Astro and imaging applications.

Sounds like an awesome solution! Very nice system.

Excellent @antoine, happy to hear that you solved it 😉 and thanks for the compliment !
Yes I fully understand the hardware that you are using 😉 Please also consider the fact that more than 99% of all APP users worldwide will not have such a system 😉 to their disposal. It must be a great pleasure to be working with such a system though 🙂 !
