June 24 2026 APP 2.0.0-beta46 has been released !

Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.

May 27 2026 APP 2.0.0-beta45 has been released !

Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

Hi am using this OSC camera . Captured lights, flats dark flats and all calibrated and registered and on stretch could see some Nebula , was also using an Optolong Lextreme. All settings at default with Winsorised selected .however when I get to registration all I see is a black screen no nebula at all? Any ideas

A black screen usually points to a data calibration issue. What happens when you integrate without calibration? You're sure you have stretch selected (on the right-hand side of APP)?

@vincent-mod

Yes stretch is ticked.

stupid question- how do I integrate without doing the calibration first - you mean just integrate Light subs only ?

@gilgm Just load the lights and no calibration. Then go straight to tab 6 and click the integrate button. APP will take care of the intermediate steps. Let us know please if the resulting image is black again. It shouldn't be.

Interesting, could you share your data with us so we can better see what might be the problem?

Go to https://upload.astropixelprocessor.com and for the username and password, use: upload

Create a directory named “gilgm-blackIntegration” and upload in there. Thank you!

Hi Wouter

 

I have uploaded 5 Light Subs as requested to the Directory 'gilgm-blackIntegration'. They are large files 117MB each.

Interestingly I didn't get a black integration. Could you check what the OpenGL button says on top-left of the APP window? And if it helps if you press that to switch GL off? Are you using APP 1.082 or higher?

That button switched off OpenGL which is used for faster processing in the image-viewer. If that helps, there is likely an issue with your graphics drivers on your system. Maybe you have a conflict with 2 drivers? Sometimes people have both Intel and NVidia etc.
