AI noise reduction to bring a new live of the old data
As may times I said it is essential to keep all your shots over the years, as you can go back and reprocess them.
Make new discoveries or improve the resulting image quality.
I recently learn about Topaz DeNoise and get it on the black Friday :) It is artificial intelligence driven software for noise reduction.
It is not designed for Astrophotography but give good results by suppressing the noise and keep the details.
Even more, it reveals some extra details, hidden into the shadows of the noise.
I had a lot of data that I shot with crazy high ISO.
So here are some process examples of stacked data, processed without applying conventional NR. I kept this as last step with Topaz DeNoise.
Recently I got one very good lens the Asahi Takumar 135mm 1:2.5. This is fast telephoto lens and from my point of view a good lens should be with aperture from 1:1,2 to 1:2,8.
Moon at 45% illumination and 70x magnification. With aperture of 200mm,14,1 stops dynamic range, color depth of 23.7 bits at this image there are slight color variation on the moon surface that reveals it’s structure.
This is the beginning of my research on how dark the sky could be and what is benefit of a dark sky for astrophotography. I was inspired from those 2 sites. First one presents mathematical model of how dark the sky is.
You can find my last DSLR Astrophotography article in Bulgarian at page 76. I am sharing my last findings for this publication, Specially written for the Institute of Astronomy.
Satellites, cosmic trash or UFOs, the moving spots are everywhere on the sky. Typical satellite behavior is to reflect sun light. It should be yellow or white and could fade and shine due to its rotation.
