NebuNoise stands out for its dedicated approach to astrophotography noise reduction, offering a simple yet powerful tool that enhances astro images while maintaining their natural beauty and detail.

How to use

Starting Up:

When you launch NebuNoise, it may take a moment to initialize. Don’t worry if the interface doesn’t appear immediately; this is a normal part of the startup process.

Selecting the AI Model:

Click on the “Select AI” button.
Locate and select the beta model file, typically named “AIx.x.pth”.
You’ll find it in the download folder, usually right next to the NebuNoise executable file.

Selecting the input image and the output directory:

Click on the “Input Image” button to upload your astrophotography image.
*Please note that, during the beta phase, the program accepts prestretched 32-bit RGB Fits images only.

The “Output Directory” is where your processed image will be saved.
By default, NebuNoise will open to the same folder as your input image. 


Use the first slider to set the intensity of the denoise effect.
Slide to the right to increase the intensity, and to the left to decrease it.

The second slider controls the sharpening of details in your image after denoising.
Similar to the denoise intensity, move the slider right to increase sharpening, and left to reduce it.

Processing Your Image:

Once you’re happy with the settings, click the “Process” button to start the denoising.
The processing may not start immediately. Please be patient and do not click multiple times; the program is working on your image.

After the processing is complete, a message will pop up to inform you.
Click “OK” on this message, and the processed image will be available in the output folder.
The processed file will have the same name as the original, but with “_processed” appended to it.
