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 Mabula,
today I installed the latest version of APP and tried to process C/2022 E3 ZTF. During registration I noticed that the button(s) for comet nucleus detection are not within my screen. Now I do realise that my screen has limited resolution, but would appreciate if you could move the button(s) so that even at this resolution they stay within view.
kind regards,
Nicolàs
Hi Mabula,
just re-installed 1.083.2. In that version the window was scaled up to accommodate the buttons:
Alternatively I wonder if it would be possible to add a button to hide the right hand panel (at this point it is not being used).
thanks and
kind regards,
Nicolàs
Thanks for reporting, we will have a look at this. We're away to London from tomorrow onwards, so please allow for a week to get a further response, sorry for the delay.
Hi Vincent,
no problem, I will be patient (but cannot wait to test the features).. 🙂
Nicolàs
And I'm back again. 😉 So I happen to notice there's a teamviewer instance running, are you looking at APP via a remote connection?
Hi Vincent, welcome back, hope you enjoyed it. 🙂
Yes, that is correct. That NUC has its own screen with a resolution of 1280 x 1024px and that is not enough to show all buttons in APP 2.0. In APP 1.083 it did work because the window was automatically stretched to something beyond 1280 pixels.
Nicolàs
It was awesome yes, short, but great after not able to do it for 3 years. 🙂
Ok, then it indeed seems a resolution issue. I'll ask Mabula.
Hi,
My workarond to this issue is to press the CFG button and then to set the image viewer in a separate window. The relevant buttons are then visible.
The change can be reversed when your comet registration is finished.
Hi @mestutters,
thanks. I just checked that and only see these options:
As there is no option to set the image viewer in a separate window in this CFG, I am not sure what you mean.
Nicolàs
hmmm, I was not awake yet, found it in version 2.0:
Will test it asap, thanks again! 🙂
Nicolàs
Hi @infinnity-deck,
I have added to our issue list that comet processing should work properly with a resolution as low as 1280 x 1024px 😉
I will work on the comet processing in the coming days and weeks so I will make sure this is fixed as well.
Mabula
