Of all the processing techniques, deconvolution is a real beast. It can work wonders, but it’s also very difficult to master. How many times I just gave up (using some unpolite words) trying to use it?
To my confort, I thought “well, calm down, … my images are noisy and of low quality, and deconvolution doesn’t like that, it only works fine with good images”. But, after some time I got to a conclusion: “If deconvolution ONLY works with good images, … what’s the point? Good images don’t really need deconvolution, do they?”
So, I decided to try again, and to devote time to apply deconvolution to my case. I chose a target which can benefit from deconvolution (the M101 galaxy), and I just took out the dust from the images I got a couple of years ago.
I’m glad to share with you my final result:
And with my conclusions, I wrote this article, hopping it can be helpful to other people out there.
