Image Description:

This is my most recent attempt at Saturn, with the notable addition of four of its brightest moons. The drizzle operation was used in IRIS to increase the image scale of the moons to be similar to that of Saturn, and then masks, levels, etc., were used in Photoshop to combine the two images. (The moons were captured with a Televue 2x Barlow at 2000mm f/10.) A higher resolution image is also availble. The images are shown with Saturn's South pole pointing up. Earth's North is as indicated with the mouseover annotation.
