Jupiter's moons

Part of the reason I bought a Nikon Z6 a few weeks ago was for the electronic viewfinder that mirrorless cameras have. In dSLR's, the image in the viewfinder takes a different path from that directed to the sensor. This can (and often, does) result in slightly out of focus images in the final result. With mirrorless cameras, what you see is what you get.

Other owners of the Z6 raved about the sensitivity of both the sensor and the viewfinder and the camera is finding its way into the hands of more and more astrophotographers as a result.

For those of us in the northern hemisphere, Jupiter is currently looming large and bright in our southern skies just after sunset. I decided to see how it would look in the viewfinder of my Z6.

I had no expectation of seeing any of the four Galilean moons (Io, Europa, Ganymede, Callisto), but as I manually focused the camera's very basic kit lens, three of them snapped into view as tiny white dots. The 4th moon, in each photo below, was either in front of or behind the planet.
