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.
I am really unsure what this is from, and the only thing I could think of is having the offset wrong. Somehow, I shot a few frames at offset of 1, instead of 50. However, the same gain was used. This is the only difference. What is worse, is that this is 27 hours worth of data, which could be pointless now.
Is there any way I can resolve this? Each image can open up individually, no problem.
Here is an image(sorry for the bad quality, I should have done a screenshot.
You shouldn't change offsets, it's something you can play around with of course, but usually a sensor has its own offset that people like to use (many times this information can be found online). Pick a nice offset (it depends, but usually I see them at 40-50) and stick with that for all exposures of your sensor. If you have images with a different offset, you need calibration files with that same offset as well. An offset of 1 is not ok though, that will likely have a huge amount black pixels and black pixels (meaning no signal at all) can never be properly calibrated.
@vincent-mod
Yeah huge mistake on my part. For osme reason my program reset and I had not even noticed that it chnaged the offset value. Is there a way I can see the offset value in APP to remove those frames??
It's usually (if your capture program added that information) found in the Fits header. If you load your image, you can look at the console window (on the left of the image window with the very small arrows). It's not mentioned in the table unfortunately.
ps. I would advice to remove those from the list, but never delete them just in case. 😉
Would it be possible to have this dialog generate a sound? Same as when an integration finishes? Nice feature when integrations that can take hours are interrupted.
I just walked away from a 500+ frame integration, only to come back two hours later to find it had stopped early on in the "Analyze Stars" step because of this dialog. Be nice to know earlier if there's a problem. Maybe a different sound for success vs. problem. But the same "I'm done" bell would be fine also.
Thanks.

Hi @timshea,
Thank you very much for your suggestion. We will add an option to the CFG menu that enables you to choose between APP stopping or continuing when encountering problems. I have added here that it should make a sound when stopping 😉

Hi all,
APP 2.0.0-beta35 has a new option called Continue on ERRORS without warnings, please check it out:
- IMPROVED continue on ERRORS without warnings
We have added a new option to the LICENSE & SETTINGS menu called continue on ERRORS without warnings. If you enable this, APP will continue processing despite possible errors on some of the light frames after steps 3) Analyse Stars, 4) Register or 5) Normalize. For instance, if you load light frames and would directly go to 6) INTEGRATE and click on integrate, APP would simply continue processing despite possible errors and it would produce an integrated result of your light frames from the frames that actually pass the steps 3), 4) and 5) without errors. Please note, the errors in this case mean regular data problems that prevent APP from processing your data normally and successfully. If an actual bug in our code occurs, APP will still stop and report the bug to the user. Please see the below screenshots, it shows the new setting in the LICENSE & SETTINGS menu, and the warning messages after 3) Analyse Stars, 4) Register or 5) Normalize will show information about this setting in the warning message, so the user can disable it if so wished.
@mabula-admin I've been away from the forums for a while due to illness, but I'm back now & wanted to say thank you for responding! I love Astro Pixel Processor, and recommend it frequently.
