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.
Hey Guys,
i like to report a Problem with APP, the Problem is since i use the Software, but now i have to report it.
If you like to save a unstreched File to a TIFF 32 or 16-Bit (without DDP) and like to strech this thing in PS, the Information in the TIFF-File is broken. Its difficult to describe. You have to go with something like Fitswork to safe the unstreched .FITS file to a TIFF-File to work correct with Photoshop or PI.
Hallo Markus.
Photoshop kann keine 32-Bit-Tiffs verarbeiten. Als 16-Bit abspeichern, dann funktionierts.
@kpsebsdorf Hallo,
Nun das ist so nicht richtig. Photoshop kann nicht alle Funktionen mit 32 Bit ausführen wohl aber den Tonwert Umfang. Und wie bereits geschrieben geht es manchmal und manchmal auch nicht.
Jeder der in PS strecht, macht dies zunächst mit der 32 Bit bevor er auf 16 Bit geht.
@detoxx PS konvertiert Tiff 32-Bit float, aber nicht 32-Bit integer. Habe aber bei meiner Version von APP (1.079) dieses Problem nicht, da dort nur in 32-Bit float bzw. 16-Bit integer aber nicht in 32 bit float abgespeichert wird (wie z.B. bie Fitswork).
@kpsebsdorf Hallo,
Danke, auch das ist mir bekannt. Er speichert Float ab, aber ich habe das oben beschriebene Problem dennoch (nicht immer)
LG
