Jupiter, taken 2019, July 15 at (PDT) 11:20:20 pm through my Dynamax 8, 2110mm f/10, telescope with a 20mm eyepiece projecting the image into my Olympus Pen-F camera at ISO 2500 and 1/30 sec. exposure. My telescope's RA drive clutch no longer engages, thus this photo was taken without tracking and hence the high ISO leaving the image a bit noisy.
Jupiter currently sits low in my southern sky in the constellation Ophiuchus, so this view is through a lot of coastal atmosphere on a clear moonlit night. Click on the image itself to see it in its full-sized glory. This is a telescope's view, inverted; I have not turned it to an upright normal view. Io, barely visible two-thirds of the way to the margin off to the left, and Europa, also barely visible close against the right margin one-third of the way up from the bottom of the photo, are the only Gallilaian moons in this photo. A pinpoint faint background star, just over one Jupiter diameter towards a "7:00 o'clock" position, demonstrates that the photo is sharply in focus. The Great Red Spot shows at mid-upper left on Jupiter's disk and some of the atmospheric bandings stands out.
