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,
If I purchase an owners licence, can I install APP on several computers I own?
For example, as I live in a light polluted place, I often take a scope and laptop for a couple of days to a dark sky sight where I would want to do some processing during the day. At home I use a desktop with a big 27" screen. Am I free to install and activate on both computers? Is there any restriction on this? - I use Sequence Generator Pro for example and I am allowed to install it on 3 computers.
cheers
Gary
Hi Gary,
Yes you can 😉
You can install APP on 3 separate computers. You can try it with the TRIAL license, it works on 3 computers as well.
With the new security system introduced in version 1.047, APP can be started and used offline as well, so without an active connection to the internet 😉
You need to activate the license on a computer online, so that the license file can be created on your computer. Then after activation, you can simply start and work with APP without an internet connection during your travels.
Let me know if you have more questions,
Cheers
Mabula
p.s. I made this a sticky 😉
Can a license be removed from a computer so APP can be activated on another computer?
Example. If I have a laptop, a desktop and a virtual machine each with a license (as 3 are allowed).
If I buy a new laptop and stop using old one for APP, can I deactivate license on old laptop so I can use APP on new laptop?
I guess if my equipment was stolen/lost/destroyed I will need to purchase a new license as I would be unable to deactivate old licenses?
Thanks.
Hi @nharvie,
Thank you for your question and welcome to the APP forum 😉
Yes it surely can. You will have to contact me to do this currently. It's no problem 😉 The license is for 3 computers, not for the 3 first activated computers.
In a future APP version, you will be able to control the activated computers yourself using the CFG (configuration) menu. Then contact with me won't be needed and it will work immediately.
Let me know if this answers your concern 😉

Hi,
I'm working together with another astro friend and I have bought the APP application.
I'm allowed to install APP on 3 computers, but when I'm installing APP on his computer is he allowed to work with APP or does he have to buy his own licences ?
Kind Regards,
TheoÂ
The licenses are individual indeed, individuals can use 3 computers (like on a processing PC and a laptop in the field, those kind of cases). Different individuals would need their own license.
Hello, I'm looking to re-install APP on my new desktop. My old system crashed badly. Where can I find my license code?
@csfapp101, as I did order or buy the APP, the license code was sent to my @mail-address, hence, your license code should also be there, deep in your mailbox, unless you did delete that email 😋 , then in that case, you should ask @mabula-admin to send your license code again to the @mail-address.
Good luck & CS
Martin
Hi @csfapp101,
I have sent your license to your registered email address, Please let me know if all is okay now.
Mabula
Thanks you. We're up and running.
