They'll be about 6 arc minutes apart (0.2 degrees) which means they'll be visible in the same field of view as a 300x telescope eyepiece/camera field or the equivalent of a telephoto lens of 15,000mm. Both planets will show notable disks in the same field of view. Because Jupiter and Saturn have large, distant orbits, they are already close to each other and will remain so for weeks afterward. However, it most areas, at sunset, the planets are low in the south-western sky and set not too long after the sun does so observing them is time-limited. In order to image them as disks in the same field (in a m4/3-FF camera) you will need a telephoto of at least 500mm focal length for a clear shot. https://www.cbc.ca/news/technology/j...tion-1.5840818 Yes, I can confirm that the Fuji-X 100-400 with 1.4 converter resolves Jupiter nicely to a disk (and shows the Gallilean moons too). I shall have mine out on the 21st. |
