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.
Can someone help me?
I got an Asi294mc pro and I used the L-enhance dualband filter and the Antlia SII-HB dualband filter.
For my M16 i have for both filters 40 frames, I extract the HA and OIII from the L-enhance filter. Also the Antlia but I did HA-OIII extract HA for the SII and HA-OIII extract OIII to get the Hb.
Now I have 4 colors and place them in the tool combine RGB, and use calculate but get a message that not all of them are compatible? Something about the depth?
How is that happened, i use the same camera,scope Asiair and for both filters they have there own flats and dark flats.
And I have the last beta 22
@stefanastro Have you tried registering and normalizing the 4 integrations together before combining since different filters were used?
@jhart after I load the frames in tab 1, I went to tab 0 to select extracting, then to 6 and integrate.
I did this with both filters so I have 4 images/colors. Or do I have to follow the steps 0 to 6?
Also is it better to load L enhance in session 1 and the antlia SII-Hb in session 2?
Does it matter that both filters has a different flat exposure time? Both had an ADU between 28k and 29.5K, i use the asi294mc pro.

EDIT, I read you post again and you say the 4 images normalize and registration, yes but I am not sure, I though I had that error again after combine them.
When you have the resulting integrated files, you can load these in again as lights, then go to normalize (tab 5) and save the normalized frames (all the way down in that tab). These saved frames can be used to combine.
@vincent-mod okay thanks Vincent.   Unfortunately i lost the SII-HB files 😫, I can't test it out. I took a screenshot of these post so I can find them back in my gallery. Â
I let you know if I take new light frames of my next DSO with SII-HB.Â
Nogmaals dank je wel, je hebt een geweldig programma gemaakt, er valt nog veel te leren voor mij.
Maar mijn SHO M16 is af sinds gisteren.Â
You're always welcome to ask on the forum, we're here to help.
Leren is leuk! 🙂
