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,
I use NINA for aquisition and from around the beginning of april, I suffer from a change in bayer pattern processing (I use a ZWO ASI1600MCC). I don't know, if the problem is inside NINA (which the devs refuse) or in APP. I always processed my files with the GRBG pattern (which is the ZWO definition), but now, I have to switch APP to GBRG, which is the upside down version. Was there a recent change of handling FITS files? This effect drives me nuts.
The NINA devs say, FITS doesn't define very well, what orientation the picture has. XISF, which is also supported by NINA has some better definition, but APP does not support XISF. Maybe, this could be a feature for future versions?
Thanks for your answer in advance!
Cheers,
Chris

Hi,
well, Cuiv, one of the devs of NINA just pointed me to the solution. It's SharpCap in which I set the flip of the image. This setting was saved in the background by the ZWO driver and NINA picked it up without any knowledge and without any chance to set it back. Because of this I lost two months of searching for the error and getting grey hair...
In the lastest BETA010 NINA will reset any flip setting in the ZWO driver.
Anyway, it would be nice, if APP would support XSIF in future. So far, only PI use it, but this isn't true anymore, NINA also can save in XISF 🙂
Clear Skies!
Chris

Fits is pretty well defined, but not always used in a good way by software. It's a format used everywhere in the astronomical science community. xifs may have some things that are positive, but we didn't see a very good reason to change that as fits can contain all the information you need. We may change that when it's used more widely, adoption seems to be very low after some years.

IC, well of course it is up to the APP-dev(s). But from (my) user's point of view, I guess, it will be more and more used. At least, I see NINA growing very fast. Evolution is working... 😎Â

Cheers and CS,

Oh definitely, when it's picked up and it becomes something quite a few users want it will get supported I think. 🙂 It's all a matter of priorities for Mabula. Hopefully I can help out in the near future.
I see Nina is opensource, very nice. I saw the latest code change to reset the flip status. 🙂
