Finally was able to take a photo of Jupiter

After many weeks of bad weather in Moscow I finally was able to take a photo of Jupiter with my 500m/F8 mirror lens.

To the left side of Jupiter - Europa and Io, to the right - Ganymede. Callisto was very faint, and didn't fit into the frame (that's because it has albedo 0.22 compared to 0.63-0.67 for Europa and Io). Current distance to Jupiter is 685 million of kilometers.

I had to tune brightness curves separately for Jupiter and it's moons because Jupiter was too bright.
