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.

Plenty of things that go wrong. Note that people either use the magic mouse where moving your finger across the mouse itself works, or they use the touch pad. I use the mouse as this is way more convenient with normal macOS use.
- right-click and the menu shows and goes away immediately. Or it goes up and disappears when you move the mouse. or it stays up, as one expects on a mac as that is the most user-friendly thing to do. This appears to be very sensitive and it has the feel of being programmed at the lowest level instead of using high-level macOS mouse events
- Scrolling the listbox with the mouse is not very nice. The columns do not stay in their spot, but are moving left and right all over the place. This makes looking for the problem files (bad star registration, bad star shapes and so on) a frustrating experience. It again appears being programmed at the lowest level, with any left-right movement resulting in a big change of column positions. Add this to the inability of the columns themselves keeping their user-assigned widths and the whole experience is one of utter frustration. This is probably the worst part of APP in terms of usability
- add setting the reference frame as a right-click menu option
- sorting on a column should be an option in the column header, by clicking on it. click again to sort the other way. Loose the sort options in the menu

I always loved to have the external trackpad and/or a regular mouse, works great in MacOS as well. But I'll have a look at why this would be the case with a magic mouse.

The file window has been much improved in the 1.083 beta 2 release. columns stay the same width, and you can move them around, and they appear to stay where they have been put. They can also be collapsed to a single point, which is nice for the info that does not change.
Thanks
