Il mistero dei riflessi blu in alcune foto dell'Apollo 14, Partendo dall'osservazione della AS14-66-9306

A dire il vero pensavo a uno dei servizi gratuiti di album fotografici online

Ho trovato questo sulla camera:

è la stessa utilizzata anche per Apollo 14??

APOLLO 14
Mission Photography
Both the surface and orbital photography of the mission served not only to document the third lunar landing and the extravehicular activities of the astronauts, but also to identify scientific areas and experiments for study on future missions. The photographic equipment and materials carried by Apollo 14 were designed specifically to
(1) photograph candidate exploration sites for potential Apollo landings;
(2) obtain vertical mapping stereo strips of regions of scientific interest and future landing sites;
(3) obtain photographs of the Lunar Module and lunar surface activities after LM landing;
(4) record mission operational activities;
(5) obtain photographed information to document the geologic samples;
(6) photograph gegenschein and zodiacal light astronomical phenomena;
and (7) acquire photographic supporting data for four orbits of Hasselblad photography and all of the Hycon Lunar Topographic Camera (LTC) photography.

The Camera Equipment
Apollo 14 carried a number of cameras for collecting data and recording various aspects of the mission.
- Two 70-millimeter still cameras with multiple lenses,
- one 16-millimeter camera with four lenses,
- and the Lunar Topographic camera were carried on the command module.
The landing module carried
- two 70-millimeter cameras with 60-millimeter lenses,
- two 16-millimeter cameras (one with a 10-millimeter lens and one with a 5-millimeter lens),
- and the 35-millimeter lunar surface close-up stereoscopic camera.

APOLLO 11
Mission Photography
The photographic equipment and materials carried by Apollo 11 were designed specifically to
(1) photograph "targets of opportunity," i.e., scientifically interesting sites and potential Apollo landing sites as time and circumstances permitted;
(2) obtain photographs of the lunar module and lunar surface activities after LM landing;
(3) obtain vertical and oblique stereo strips of nearside and farside regions of scientific interest;
(4) record mission operational activities; and (5) obtain documentation for subsequent landing crew training purposes.

The Camera Equipment
Apollo 11 carried a number of cameras for collecting data and recording various aspects of the mission, including
- one 70-mm Hasselblad electric camera,
- two 70-mm lunar surface superwide-angle cameras,
- one Hasselblad El data camera,
- two 16-mm Maurer data acquisiton cameras,
- one 35-mm surface close-up stereoscopic camera, and a television camera

Per 11 e 14 vale la stessa immagine:

4.5 DIM-LIGHT PHOTOGRAPHY

Low-brightness astronomical light sources were photographed using the 16-mm data acquisition camera with the 18-mm lens. The sources included the zodiacal light, the galactic light, the lunar libration region (L 4 ) and the dark side of the earth.

All star fields have been readily identified and camera pointing appears to have been within one degree of the desired aiming points with less than one-third of a degree of image motion for fixed positions. This is well within the limits requested prior to flight, and it confirms that longer exposures, which had been originally desired, will be possible for studies such as these on future Apollo missions. The zodiacal light is apparent to the unaided eye on at least half of the appropriate frames. The galactic light survey and lunar libration frames are faint and will require careful work. Earthdarkside frames of lightning patterns, earth-darkside photography during transearth coast, and S-IVB photographs were overexposed and are unusable.
