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.
This horrible new feature is very invasive. It continually pops up in my face taking up half the screen, even if I move it out of the way. With my mosaics I must to be able to "blink" between a single registered frame and the final mosaic to see which panels might be misaligned, missing or need more data. The new Tool Output no longer makes this possible.  I am reverting back to beta 14 for now until there is a way to disable or hide it completely.
Edit by Mabula, will be fixed in 2.0.0-beta16
Hi @kelvin-hennessy,
Thank you very much for reporting this, I will check and fix a.s.a.p. So at what stage are you trying to do this? After 4) Register I assume?
Ah, yes, you are right, when you move the chart away and reload a new image, it will show the chart again. I will fix this immediately.

Hi @kelvin-hennessy,
I have fixed this behaviour for beta16, will try to get it released a.s.a.p.
Mabula
Hi @kelvin-hennessy,
Please download and check beta16, i have improved it's behaviour now 😉
Mabula
@mabula-admin Thanks very much - I've installed it and doing another run on the same mosaic today - I'll let you know how it goes. (it takes 12 hours for registration and integration on a fast computer ! )Â Â I'm acquiring replacement data for some of my panes poorly captured & documented last year. I have to plate solve the bad panels to determine their centres so I can re-capture them.
@mabula-admin The good news is that appears on beta 16 that the analytical results will not jump out and stays hidden if desired. Also the "Cancel" button has stayed visible all the time too.
Â
The bad new is that beta16 is horribly slow - my latest integration took about 27 hours vs typical 12 hours.  Also when I try to view any panes of the mosaic in registered view it just took 20 minutes to display the pane, waiting at the "loading new image into image viewer" all that time. The CPU sits on 1-2% all this time. Â
So I will need to revert back to the last useful version which was beta 14
Â
I have just ordered a new super fast Samsung 990 Pro 2TB PCIe SSD that should arrive tomorrow as I am finding it hard to keep 768GB free on my 1 terabyte C: drive - plus it will eliminate the SSD as a possible cause of the problem. As another member commented I will disable overclocking as well. and try beta 16 again on the weekend.

Thanks Kelvin @kelvin-hennessy for confirming that beta16 fixed the annoying chart from appearing each time. Yes, cancel button should be very clear now 😉
Like indicated in your other topic. Nothing changed in beta16 for cpu resources or memory management with regard to both beta15 and beta14. So the difference in speed comes from the actual settings used in APP and the choice of reference for your mosaic. Do you project the mosaic with the calibrated projective model?
Mabula
Â
@mabula-admin I use calibrated projective with the mercator projection. That's reassuring to know nothing has changed from a programming point of view - so the software may have not liked the big gap in the Milky Way. I'm hoping to acquire my final 3 panes of the mosaic tonight if the skies clear a bit more and I will start off another run with Beta 16 using the correct reference pane.
