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 have tried all of the suggestions that come with that pop up notice that registration has failed. I am using data downloaded from Telescope Live for the Bode's galaxy.
Perhaps I don't understand the process well and do not know what I am doing. since I am still very new to this. This happens with some images but not others.
What can I do to fix it?
Thanks kfor yourd help. I know you are very busy
No problem Terry, that's why we're here. 🙂
Could you give a bit more information about the type of data and what exactly is going wrong?
There were 18 calibrated images and with a total of 90 minutes of exposure on the SPA 2 telescope. The breakout was: Blue, 5 images of 300 seconds each; 4 images of 300 secs each of Green; Red was 5 images of 300 secs each and Luminance was 4 images of 300 seconds. I used all the default settings on the registration tab, though when the error message poped up. I did try to change some of settings on the ones mentioned in the message but did not get a different result. 16 of the 18 Light images failed on the Registration tab.
All the images came from Telescope Live data.
I also had an error message pop up on another Telescope Live M66 image but with the Analysis tab, which I had never had happen before.
I have been able to process other images without such error messages. Makes me wonder if the data is somehow corrupted that I am getting or if I am not doing something right or needing to adjust some settings.
I so much appreciate your help.
I frogot tO mention I use a MAC desktop with the latest version BIG SUR.
Mm, so if resgistration is failing then maybe it's due to bad data indeed. Might be an issue with calibration data as I've seen that go wrong a lot with online services. Could you maybe post a screenshot of the masterdark, masterbias and a light sub from the data that is giving issues?
Here are the images you requested I hope! Let me. know what I have missed. H
Hope these give some insight into the problem.
This is the first time I have worked with screenshots so I hope I have done it right
Well the screenshots worked, but I meant to show me the actual Dark and a light frame, just to see how that looks like for me to get an idea. 🙂 Otherwise you can also upload some data to our server, whichever you prefer.
Thanks for being patient with me. I will send you the frames as soon as I can. This is all so new to me in seeking to understand the vocabulary and using the app correctly. I am determined to do it no matter how long it takes . I am so inspired by the images I see others develop
No problem at all Terry, would love to see you get into it even better. 🙂
Go to https://upload.astropixelprocessor.com and use upload1 as username and upload1 as password.
Create a directory named "tsnapp-regfailure” and upload in there. Thank you!
Dear Vincent, I got the same Problems yesterday. There is no problem to stack using Luminar or SiriL. I do not want to trash too much pictures. It was a long night to shoot them 😎
so what's the best Workarround to avoid that Error?

Peter
@astropaulchen What version of APP are you using? Is it 1.083-beta2? If yes please try 1.083-beta1.
Dear Wouter,
you are right: I use beta 2. o.k. I will load beta 1 and come back to you with my experience.
thank you
Peter
P.S. another question: how can I save a project. / its state / a snapshot? yesterday evening it was too late to work my nebula to an end. So I stopped. Accidentally somebody switched of my Computer and after restarting APP there was a blank screen and I had to beginn from scratch. 😫
I am sorry - but I can't find a download page for 1.083 beta1 - can you mail me a link?
Peter
@astropaulchen Regarding saving a project: this is not possible yet. It will be made available in a future version.
For a download link for 1.083-beta1, see the top of any forum page.
