Range :  34 million km. ( 21.1 million miles) P-22993C This Voyager 1 photograph of Saturn was taken on the last day it could be captured within a single narrow angle camera frame as the spacecraft neared the planet for it's closest approach on Nov. 12, 1980. Dione, one of Saturn's innermost satellites, appears as three color spots just below  the planet's south pole. An abundance of previously unseen detail is apparent in the rings. For example, a gap in the dark, innermst ring, C-ring or Crepe Ring, is clearly shown. Also, material is seen inside the relatively wide Cassini Division, seperating  the middle, B-ring from the outermost ring, the A-ring. The Encke division is shown near the outer edge of A-ring. The detail in the ring's shadows cast on the planet is of particular interest. The broad dark band near the equator is the shadow of B-ring. The thinner, brighter line just to the south is the shadow  of the less dense A-ring. ARC-1980-AC80-7003

Range:  72.3 million km. ( 44.9 million miles ) P-29314B/W This Voyager 2 photograph of Uranus shows the planets outermost, or epsilon, ring.  This is a computerized summation of six images shot by the narrow angle camera. It is the first photo to show the epsilon ring unblurred by Earth's atmosphere. The Epsilon ring, some 51,200 km. ( 31,800 miles )  from the planets center, is the most prominent of Uranus' nine known rings. Ground based observations of stellar occulations by the rings have determined that the Epsilon ring is eccentric, or elliptical, with its widest portion  about 100 km. ( 60 miles ) wide and its narrowest portion about 20 km. (12 miles ). Estimates of the rings brightness suggest that it is also very dark, with a reflectance of only 1 or 2  percent and a probable  composition of carbonaceous material similiar to that on dark asteroids and the dark side of Saturn's moon Lapetus. Because the ring is so narrow and dark, at this range,  the Voyager camera could not  resolve even the widest part,  resulting in long exposure times so obtain a good image. six exposures of 11 or 15 second duration were added together by computer to produce this image.  In this image, the central  portion is greatly overexposed. Various artifacts due to electronic effects  and image proccessing can be seen in the central portion of the frame, including the dark image just above the planets image, the diffuse brightening below it and the small, bright projection from the edge of the planet in the upper left. The ring is distinctly less prominent in the lower left portion and more prominent in the upper right. This is in agreement with the predicted locations of the narrow and wide portions of the ring, respectively. ARC-1985-A86-7001

Range : 2.77 million miles (1.72 million miles) resolution :  51 km. (32 mi.) P-29495C This Voyager 2 photograph of the outermost Uranian satellite, Oberon  is a computer reconstruction of three frames , exposed through the narrow angle camera's blue, green, and orange filters. the grayness or apparent lack of strong color is a distinctive characteristic of the satellites and the rings of Uranus and can serve as one indicator of the possible composition of the satellites' surfaces. Oberon has a diameter of about 1,600 km. (1,000 mi.) and orbits the planet at a radial distance of 586,000 km. (364,000 mi.). Oberon's surface displays areas of lighter and darker material, probably associated in part with impact craters formed during its long exposure to bombardment by cosmic debris. Thr resolution of this particular image is not sufficient, however,  to reveal with confidece  the nature of these features. ARC-1986-AC86-7012

Range : 2.52 million miles (1.56 million miles) P-29481B/W Voyager 2 returned this photograph with all nine known Uranus rings visible from a 15 sec. exposure through the narrow angle camera. The rings are quite dark and very narrow. The most prominent and outermost of the nine, Epsilon, is seen at top. The next three in toward Uranus, called Delta, Gamma, and Eta, are much fainter and more narrow than Epsilon ring. Then come Beta and Alpha rings, and finally, the innermost grouping, known simply as the 4,5, & 6 rings. The last three are very faint and are at the limit of detection for the Voyager camera. Uranus' rings range in width from about 100 km. (60 mi.) at the widest part of the Epsilon ring, to only a few kilometers for most of the others. this iamge was processed to enhance narrow features; the bright dots are imperfections on the camera detector. The resolution scale is about 50 km. (30 mi.) ARC-1986-A86-7011

Range :  660,000 km. ( 412,000 miles ) P-34711 This Voyager 2 wide angle photograph shows the shadow of Neptune on the rings. Because Neptune's shadow casts a curved profile on the rings which does not quite reach out to the outermost ring at about 38,000 km. (24,000 miles) from the cloudtops. In this photo, taken through the clear filter at a phase angle of about 135 degrees, the shadow does fall on the inner bright ring ( at about 28,000 km. (18,000 miles) from the cloudtops. The shadow also clearly delineates the radial  extent of the broad sheet of material discovered extending from about halfway between the bright rings down to, and perhaps beyond the inner bright ring. A very thin, brighter of the edge of this diffuse sheet can also be seen. additional information from other images indicates that this faint material extends further in, to at least the position of the innermost faint ring discovered at about 17,000 km (11,000 mi.) from the cloudtops.
