Currently, Jupiter is in opposition to the earth which means that it is closest to the earth.

Jupiter is a giant gas planet. It is the largest planet in the solar system, larger and more massive than all the other planets combined, and the fifth planet by its distance from the Sun (after Mercury, Venus, Earth and Mars).  

Taking into account the average atmospheric agitation (3/5), we can appreciate a good resolution of the planet. Considering the transparency of the sky which is 5/5, the contrasts of the planet are very good.  

The challenge here is to photograph the planet before it rotates, to preserve detail, its full rotation being only 9,83 hours. While performing the calculations, I had to take the images in a maximum time of 76 seconds (1,3 minutes). As my camera is monochrome, you have to take 3 images (red, green and blue) to reconstruct the colors of the planet. Which adds to the challenge. To save time, I produced a synthetic green image using the composite red and blue images. So I took 1 images for each of the red and blue colors in addition to manually turning the filter wheel! By selecting the best 500 images of each of the red and blue colors, it allowed me to have a final image with little turbulence, contributing to fine detail.
