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.
Mabula,

is there a way to reset the sliders on the right side to their original setting? sometimes i grab the wrong slider (the one below the text...) and then i screw up my settings. Or do you have to reload the file then?
thanks!

Hi Michel,
Yes, there is, there are several options,
- disable and then enable auto DPP using the "auto" selectbox
- or choose a new auto DPP preset and then the old one again.
In both options the image doesn't need to be reloaded, probably the first option is the easiest ?
Cheers,
Mabula

I set all the sliders to one side as a test, then disabled and enabled the DPP and Auto boxed. I see no difference, in other words I don't see the sliders reset at all.
I just started using the trial version and would like to get the program reset before I attempt another processing session.

Thanks.

If you changed saturation or something, that isn't reset, the stretch slider can be reset with the reset button, and switching profiles. Restarting APP would be fastest I think if you don't remember what slider you changed.
Hi,
Unfortunately, the suggestions above are incomplete:
- disable and then enable auto DPP using the "auto" selectbox
- or choose a new auto DPP preset and then the old one again.
These actions only reset the ST and BA sliders. The sliders below them (HA, Con, Sharp, etc.) stay where they are. Is there any way to reset them to their default values without restarting APP?
Also, what is the "Reset" button (in the panel with the B/W/G sliders) intended to do? I don't see that it actually resets any of those sliders.
Thanks
Unfortunately not, the reset is just for 1 setting basically at the moment.
Thanks Vincent, I'll stop searching then! 😀Â
Forgive my ignorance in asking this, but is there a forum section specifically for proposing enhancements for consideration?
Yes, here's the section; https://www.astropixelprocessor.com/community/rfcs-request-for-changes/
However, we will always let Mabula know about changes that may be very interesting to put onto his todo-list. The UI in your case is 1 of the changes considered.
