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 there,
we (another Astro photographer and I) want to put our integrated lights together. To get a photo with a lot of exposure time.
Of course we have different cameras and telescopes.
Is it possible to do this with Astro Pixel Processor?
If so, how? 🙂
Good idea! - just chiming in here to get updates.
I don't know about different scopes, but different cameras yes. At least I was able to integrate raw files from both my unmodded D5300 and modded D5100. Oh course, they are similar, and I shot through the same scope (Celestron C8), but it worked. Good luck!
I have done it in the past with different scopes and cameras.
I tried to put two photos together. Unfortunately, the registration does not work perfectly. An APO teleskope does not fit perfectly with a mirror telescope.
I'm kind of surprised its that far off. Did you use "dynamic distortion correction" in the registration tab? And uncheck "same camera and optics"
Yes have tried all of these options. With and without. I experimented. However, it never became perfect.
Yes this is possible, we've made integrations of >5-10 different setups and combined them in APP automatically. It's one of its strengths even. It does become easier when each setup has nicely corrected data ofcourse, if one of them is distorted, that might be an issue. That would be an issue for any package though. So could you post an integration of the mirror scope and one of your setup here?
Dropbox File (Private or Invalid)Great, thanks, I'll download them and will come back to you.
Could you procide me with the fits of both maybe? That would give me more information. But anway, was one of them mono and the other color? The M78_RAW_stack produces a very weird histogram in RGB. I'll experiment a little. 🙂
The file M78_RAW_stack is from the Astro colleague. He wrote me:
the histogram is shot for me because my flats are not color neutral. Therefore here is a red cast in the pictures ....
Equipment:
Esprit100 at F4.3
ASI1600MC-Pro
The other file is from me. I use the Skytatcher 200/1000 PDS with comacorrector and the Canon 5D MK IV.
