Tom,
Great images. How did you keep the dew off your mirror?

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.
