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.
Hello Fellows Astrophotographers ...
After long time im returned in our great hobby...
Have anyone found or create a workflow processing data from ocs and narrowband filters from scratch to finish ?

Hi Stratos @hyperion,
Glad to hear that you are back here !
I am here to help you. I do not directly have a workflow sheet for you, but I would suggest the following:
1) Download the latest APP version if you haven't done so yet from our Downloads section at https://www.astropixelprocessor.com/downloads/ (and activate your license if needed).
2) OSC and narrowband filters, you will need to check the menu 0) COLOR SETTINGS, this is the old RAW/FITS menu.
Use the appropriate debayer/x-Trans algorihthms for your narrowband filters. If you were using Multi-Narrowband filters, check out the new Multi-NB algorithms. Explanations are in the popup windows. Let me know if you need assistance or any clarification.
3) Create the integrations per Narrowband wavelength.
4) Load the integrations per NB wavelength (Ha, O3, etc) into the RGB Combine Tool to make the RGB composite of your choice.
Let me know if you have any question.

Hey Again Dear Mabula...
Great to find you again here ...
my setup is ocs and two narrowband filters,
one have wavelength H-a , H-b and OIII
the other i use it like RGB is light polution filter.
The first question is that i must use algorithm multi NB extract H-a & H-b (will extract two files H-a and H-b)?
that will combine like one file in HaOIIIRGB Combine tool ,
or multi NB extract H-a and multi NB extract OIII like the previous versions.
im searching to find which is the best workflow to processing files from ocs and narrowband filters ...
Thanks Again Mabula

Any help from Fellows astrophotographers that using Narrowband filters and osc will be welcomed… some basic workflow that explains how to combine files from light pollution filter (use it like RGB) and files from Narrowband filter (H-a , H-b , OIII)

Indeed, have you tried it? How is processing going? Let me know how I can assist 😉
