 I have a picture here of planets that I want to process with the GIMP and I do this rarely so I'm going to record this so that I can later redo this if I have other similar pictures. So this is a picture that I took a couple of days after the great conjunction of the planets Saturn and Jupiter here in 2020. I think I took the picture with my camera and strong zoom the 26th of December 2020 and what you see here is Jupiter with two moons and Saturn and I want to process this picture. So let's zoom in. So here I have Jupiter with two moons Io and Calisto if I'm not mistaken and here Saturn. Now the processing that I wanted to do here is with the threshold tool have clear blobs that represent the planets. And as you can see I lose one of the satellites of Jupiter here it is. But when this appears then the other one merges with the Jupiter itself so what I did. So what I did here and just to be clear I'm not an expert at all in this. I selected this part went to filters and hounds sharpen and here made some changes to the radius and amount okay like this then I did the same for Calisto okay then select everything and then here in colors do the threshold like this. And now I have black and white very high contrast with Jupiter it's two moons and Saturn.
