The detail of Earth 🌍 captured in Bill Anders’ first color photo taken from lunar orbit on #christmaseve in 1968 #OTD really is amazing. This is a crop of AS08-14-2383, in its original orientation, from a scanned 70mm @nasa film original 16-bit TIFF file by a project team at Arizona State University

Remember, JunoCam was simply a public relations device. It was NOT placed in an area of the spacecraft that was very well shielded from radiation exposure, meant to last only perhaps eight close passes. Yet it's lasted all this time. Incredible!

Saturn's tiny icy moon Mimas hangs in space against a backdrop of the giant planet itself.
The rings cross the bottom of the view, and cast their shadows onto the planet beyond.

No new JunoCam images have appeared since July but there are many older, spectacular images I still haven't processed. I processed this one recently. This is from the PJ14_21 raw image data obtained on July 16, 2018. Approx true color/contrast and enhanced versions. North is to the upper left.

Jupiter on Saturday morning in good seeing using the C11 with x2 Barlow.
I'd just recollimated the scope and cleaned the corrector plate, which I think helps, but the dew was awful!
This is probably my best Jupiter image to date.
More data still to go through
