Noise Reduction and Sharpening

Astrophotography requires specialized techniques to reduce image noise and improve definition, without each destroying the other.

 

 

 

On our journey through critical PixInsight processes, noise reduction and sharpening are the next stop. These are two sides of the same coin; sharpening often makes image noise more obvious and noise reduction often reduces the apparent sharpness. Considering them both at the same time makes sense, as the optimum adjustment is always a balance between the two.

Both processes employ unique tools but share some too. They are often deployed a little during linear and non-linear processing for best effect. These are uniquely applied to different parts of the image to achieve the ...
