Our Moon Close in Line with Jupiter

Our Moon at first quarter and close to conjunction with Jupiter through very thin high cloud on the evening of 2019, September 5 at PST 9:17:40 pm with Olympus Pen-F at ISO 500 and 1/50 sec. through E.Zuiko-T f=250mm 1:5 fully open at f/5.
Lying low to my south-southwest, the Moon and Jupiter showed very nicely through the very high thin evening cloud. At this magnification, Jupiter appears as a very tiny but definite disk and shows some colour in contrast with the white of the moon. Click on the image to view it in its full sized glory.

First Attempt at Planetary Astrophotography, Jupiter




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.
