Subject: [AZ-Observing] Jupiter and Ganymede This Morning

With the humidity near 100% and not a breath of air movement, we had some 
decent seeing this morning.  I wheeled the 15-inch out into the driveway to 
watch Ganymede pass in front of Jupiter.  These images were taken with a ZWO 
ASI120MM camera, with the scope Barlowed up to 5500mm of focal length.  Then I 
doubled the image size in the processing so you can view it across the room.  
Image scale is 0.071 arcsec/pixel after resampling.

The bright spot at the bottom of Ganymede is Osirus, while the broader, dark 
area at upper right is Galileo Regio.
