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.
Dag allemaal,Â
Heb een ZWO 2600MC en de ZWO 294mc en beide kleuren camera's. Met de nieuwste versie van APP krijg ik na het stapelen van lights,darks, flat of bias een zwart wit foto en idem dito ook met de vorige versie. Met alles laden klik ik op 0 en zet het op RBBG en bij Algorithm No interpolation. Dan Intergrate en nadat alles is gestapeld is er geen kleur te zien en met APP bewerken krijg ik de melding dat het niet mogelijk is met een zw foto!! Ik doe wat verkeerd en wie kan een advies geven alstublieft? Alvast hartelijk bedankt.Â
Mvg PeterÂ
Edit By Mabula:
Hi all,
I have a ZWO 2600MC and the 294MC, both OSC/color camera's. With the latest APP version I get a black and white/monochrome image, also with previous versions. When I have loaded all lights and calibration data, i set the Bayer pattern to RBBG in 0) RAW/FITS and I set the bayer algorithm to No interpolation. Once integrated, there is no color, what am I doing wrong?
Kind regards Peter

Hoi Peter, bedankt voor je post op ons forum en tevens welkom !
Omdat je het algoritme op no interpolation zet, krijg je een zwart wit foto. Dat is precies de bedoeling. Het no interpolation algoritme zorgt ervoor dat APP juist niet de kleuren gaat maken. Dus om de kleuren te krijgen laat je het algoritme het best op de default staat van Adaptive Airy Disc, dan moet je een correct kleuren resultaat krijgen. Ik hoor graag of het probleem daarmee is opgelost?
Hi Peter, thanks for your post and welcome to our forum !
Because you have set the algorithm to no interpolation, you will get a monochrome/black&white result. That is expected behaviour with the no interpolation setting, i will treat the data as being monochrome. So to get a correct color result, it will be better to use the default demosaic algorithm of Adaptive Airy Disc. Then you will get a color result. Please let me know it this solves the issue.
