Apollo 16
Photographic Equipment
A number of cameras of various types were carried on each Apollo
mission, to allow the crew to make scientific observations, and to
record the mission for posterity. Still and motion pictures were
made of most space craft maneuvers and crew lunar surface
activities. During lunar surface operations, the emphasis was on
documenting the placement of lunar surface experiments, documenting
lunar samples, and on recording in their natural state the lunar
surface features.
Command module lunar orbit photographic tasks and experiments included
high-resolution photography to support future landing missions,
photography of surface features of special scientific interest and
astronomical phenomena
The camera equipment stowed in the Apollo 16 Command Module comprised
one 70 Hasselblad electric camera, a 16mm Maurer motion picture camera,
and a 35mm Nikon F single-lens reflex camera. The Command Module
Hasselblad electric camera was normally fitted with an 80mm f/2.8 Zeiss
Planar lens, but a bayonet-mount 250mm lens could be fitted for
long-distance Earth/Moon photos. A 105mm f/4.3 Zeiss UV Sonnar was
provided for an ultraviolet photography experiment. More details
of the Hasselblad cameras are given in
Apollo 11
Hasselblad Cameras by Phill Parker
The 35mm Nikon F was fitted with a 55mm f/l.2 lens for astronomical and
dim-light photographic experiments.
The Maurer 16mm motion picture camera in the Command Module had lenses
of 10, 18 and 75mm focal length available. Accessories included a
right-angle mirror, a power cable and a sextant adapter which allowed
the camera to film through the navigation sextant optical system.
The cameras stowed in the Lunar Module were two 70mm Hasselblad data
cameras fitted with 60mm Zeiss Metric lenses, an electric Hasselblad
with a 500mm lens and two 16mm Maurer motion picture cameras with 10mm
lenses. One of the Hasselblads and one of the motion picture cameras
were stowed in the modular equipment stowage assembly (MESA) in the LM
descent stage.
The LM Hasselblads had crew chest mounts that fit dovetail brackets on
the crewmanÂs remote control unit, thereby leaving both hands free. One
of the LM motion picture cameras was mounted in the right-hand
window to record descent, landing, ascent and rendezvous. The 16mm
camera stowed in the MESA was also carried aboard the lunar roving
vehicle to record portions of the three EVAs.
Other cameras were fitted in the CM Scietific Instrumentation Module
Bay, and with the lunar surface experiments. These are described
separately.

The detailed description of the Cameras and their accessories is taken
from the Apollo Operations Handbook Section 2.12.5.3.
Two basic types of operational cameras and associated accessories are
furnished to facilitate general purpose in-flight photography: a 16mm
cine/pulse camera and a 70mm still camera. In addition,
photography of the moon is accomplished with the lunar topographical
camera (LTC). Photography assignments vary from mission to
mission and hardware requirements vary accordingly. Spacecraft crew
equipment stowage lists reflect camera equipment configuration. Typical
mission photography task assignments include the following: synoptic
terrain and weather studies, LM docking, crew operations, crew EVA, and
targets of opportunity. Later manned flights will provide for specific
scientific experiments and will require specialized equipment which is
described in section 2.11. A brief description of the two basic
operational cameras, the LTC, and their accessories follows.
16 mm Data Acquisition Camera
The Data Acquisition Camera is a modified movie camera and is an
improved version of the earlier Gemini-type 16mm sequence camera
equipped with new-type external film magazines which greatly enhance
the photographic capabilities. Primary use of the camera is to
obtain sequential photographic data during manned flights. It is
used for documentary photography of crew activity within the CM and for
recording scenes exterior to the spacecraft. Bracketry
installations at each rendezvous window facilitate use of the camera
for CSM-LM docking photography to recording engineering data.
Camera modes of operation (frame rates) are variable as follows: time,
1 frame per second (fps), 6 fps, 12 fps, and 24 fps. Shutter
speeds are independent of frame rate and include 1/60 second, 1/125
second, 1/250 second, 1/500 second and 1/1000 second. Camera
power is obtained from the spacecraft electrical system via
panel-mounted 28-vdc utility receptacles. Camera operation is
manually controlled by an 0n-Off switch located on the front of the
camera. Camera weight, less film magazine, is 1.8 pounds (0.8
kg). When mounted at either spacecraft rendezvous window, the
camera line of sight is parallel (+2 degrees) to the CM
X-axis. Camera accessories include a power cable, film magazines,
lenses, right angle mirror, and a ring sight, which are described in
the following paragraphs. The remote control cable, described with the
70 mm electric Hasselblad camera accessories, can also be used with the
16mm Data Acquisition Camera.
Power
Cable. The power cable provides the necessary connection
between the spacecraft electrical power system and the 16 mm
camera. The cable is approximately 108 inches (2.74m) long and
weighs approximately 0.23 pound (0.4kg). 28 volt dc utility receptacles
are located on spacecraft panels 15, 16, and 100.
16 mm
Film Magazine. Film for each mission is supplied in
preloaded film magazines that may be easily installed and/or removed
from the camera by a gloved crew member. Film capacity is 130 feet (
40m) of thin base film. Total weight of magazine with film is
approximately one pound (0.4kg). Magazine run time versus frame rate is
from 87 minutes at one fps to 3.6 minutes at 24 fps. Each magazine has
a Âfilm remaining indicator plus an end of film red indicator light.
Future plans include film magazines of 400-foot capacity. Quantity and
type of film supplied is determined by mission requirements.
Lenses.
Three lenses of different focal length are provided for use on the 16
mm camera.
10 mm.
A medium wide-angle lens, the field of view being 41.1 degrees x 54.9
degrees. It is used for internal crew activities and equipment when
details are required. Focus is from 6 inches to infinity with aperture
openings from f 1.8 to 22. It has two spike-like handles for setting
f-stop and distance with the gloved hands.
18 mm
Kern. A lens of slightly wide-angle design and high
optical quality. Primary use is for vehicle-to-vehicle
photography while bracket-mounted at left or right rendezvous window.
It is also the widest angle lens that may be used with the right-angle
mirror. This lens is usually stowed on the camera. Viewing angle of 24
x 32 degrees and weight is approximately 0.80 pound and has two
spike-like handles for setting the f-stop and distance with the gloved
hand. This improved lens has larger numbers for reading while in the EV
spacesuit.
75mm
Kern. A medium telephoto lens design with excellent optical
properties. Primary use is for photography of distant objects and
ground terrain. Usually used on the window-mounted camera. Viewing
angle of 6 x 8 degrees, weight is approximately 0.80 pound. This lens
is similar in appearance to the new 18 mm lens and has two handles for
f-stop and distance, gloved hand settings, and larger printed numbers.
It also has a sun shade.
Right
Angle Mirror. This accessory, when attached to the
bracket- mounted 16 mm camera and lens, facilitates photography through
the spacecraft rendezvous windows along a line of sight parallel to the
CM X-axis with a minimum of interference to the crewmen. It adapts to
the 18 m and 75 mm lenses by means of bayonet fittings.
Ring
Sight. An accessory used on the 16 mm camera as an aiming aid
when the camera is hand-held. The concentric light and dark circular
rings, as seen superimposed on the view, aid the user in determining
the angular field of view of the sight. It is attached to the camera by
its shoe sliding into a C rail. It is also used on the 70 mm camera.
Data
Acquisition Camera Mount. This device facilitates in-flight
mounting of the 16mm camera at the spacecraftÂs left or right
rendezvous windows during zero g. The mount is a quick-disconnect
hand-grip that may be attached to a dovetail adapter at either
rendezvous window. The camera attaches to the mount by means of a
sliding rail and a friction lock screwed against the camera by a
knob. Two marked locating stops are provided for correct
positioning of the camera at a window, one for the 18 mm lens and one
for the 75 mm lens. Mount alignment is such that installed camera/lens
line of sight is parallel to the CM X-axis, +1 degree.
16mm
Camera Sextant Adapter. The 16mm camera can be used to
take photographs of the moon through the CM sextant during lunar orbit,
useing camera sextant adapter. The adapter is an optical unit about 8
inches long that mounts directly on the Guidance and Nav Panel 122 SXT
socket. The camera attaches to the adapter by means of a bayonet
fitting.
DAC Timing Cable. The
DAC timing cable function is to
supply 28 vdc to the 16 mm DAC and route the shutter closure signal to
the RHEB panel 227 and the PCM junction box. The DAC timing cable
is
32 inches long with a connector at each end. The DAC connector has an
orange index mark and is labeled P1 - DAC PWR. The connector for panel
227 is a large 90 elbow, has a blue grey index mark, and is labeled P2
- PNL 227. At launch, the cable is coiled, secured with a utility
strap, and stowed in L2. After mounting the DAC in the right rendezvous
window, the DAC timing cable is unstowed and the connector (P1 - DAC
PWR) is mated to the camera. The SC1 INST PWR switch on panel 227 is
verified in the OFF position, the cable connector (P2) is connected to
the panel receptacle, and the panel switch is placed to the PWR
position. The shutter closure signal is sent to the PCM junction box
when the camera is operating.
16mm Camera Operation.
The camera mount (grip) is removed from stowage and attached to the
dovetail at the appropriate rendezvous window. The 16mm camera and
accessories are unstowed as required. The selected lens is
attached. An optional right-angle mirror may be installed on the
lens. A ring sight may also be installed on the camera for
hand-held use. A film magazine is installed on camera. The
correct exposure is determined. The lens aperture and focus are
set. The camera mode (frame rate) and shutter speed are
set. The power cable is installed on camera. If required, the
camera is installed in the mount at the window. The Utility
Power receptacle switch is set to Off, the camera power cable is
connected to the appropriate receptacle and the Utility Switch is
placed to the Power position. Filming operation can be started by
pressing the Operate button (switch) on the front of the camera. To
stop the camera, the Operate button is pressed again. .
70mm Hasselblad Electric Camera
(HEC)
The 70mm camera is primarily used for high resolution still photography
and is hand-held or bracket mounted. Camera features include inter
changeable lenses and film magazines. The standard lens is an 80 m
f/2.8, and 250 mm f/4 and 500 mm f/8 telephoto lenses are provided for
photography of distant objects. Two types of 70mm film magazines are
provided, one for standard-base films, the other for thin-base
films. Camera accessories include filters and a ring sight.
Some specific uses of the camera are as follows:
 Verify landmark tracking
 Lunar landmark and mapping
 Record Saturn IVB separation
 Photograph disturbed weather regions (hurricanes, typhoons, etc.),
debris collection on the spacecraft windows, SLA separation, LM during
rendezvous and docking, terrain of geological and oceanographic
interests, and other space equipment in orbit
 Act as a backup to the 16 mm sequence camera
 Record in-cockpit operation, e.g., normal positions of suited crewmen.
A built-in 6.25-vdc battery-powered, electric-motor-driven mechanism
advances the film and cocks the shutter whenever the actuation button
is pressed. An accessory connector permits remote camera operation and
shutter operation indication for time correlation. The weight of the
camera, with 80 mm lens and 2 batteries, without film magazine, is 4.04
pounds.

The camera accessories are:
80 mm
f/2.8 Lens. Standard or normal lens for the 70 mm camera
with 2-1/4 x 2-1/4-inch film format. Used for general still
photography when a wide angle or telephoto view is not required.
Focuses from 3 feet to infinity. Has built-in shutter with speeds
from 1 second to 1/500 second. Field of view, each side, is
approximately 38 x 38 degrees.
250 mm f/5.6 Lens. A telephoto
lens that is primarily used for photography of terrain and distant
objects. It produces a 3X magnification over the standard 80 mm
lens. The relatively narrow view of this lens necessitates careful
aiming of the camera to ensure that the desired scene is
photographed. A mount is available for mounting the camera and
lens at the right rendezvous window to view parallel to vehicle X-axis.
The lens focuses from 8.5 feet to infinity, and has built-in shutter
with speeds from 1 second to 1/500 second. The field of view is
approximately 13 x 13 degrees. The weight of the lens is 2.06 pounds.
Remote Control Cable. The
function of the remote control cable is to actuate the shutter from the
left couch while sighting targets through the COAS in the left
rendezvous window. The cable is 48 inches long with a handle,
button, and control knob at one end and a connector at the other. The
control knob has settings of TE (time exposure), 1, 6, 12, and 24 fps.
70 mm Film Magazines. Two
types of film magazines are used, one for standard-base film, the other
for thin-base film. Either film magazine attaches to rear of camera and
is locked in place by a lever-actuated clamp. The type 100 film
magazine is for standard-base film and its capacity is 100 2-1/4 x
2-1/4 inch frames. The type 200 film magazine is for thin-base film and
its capacity is 200 2-1/4 x 2-1/4 inch frames. Each film magazine
contains gross-film indicators for frame count.
Lunar Surface 70 mm Film Magazine.
The lunar surface 70mm film magazines are standard 70 mm magazines that
have a thermal protective coating. They are stowed in the 70mm magazine
LM transfer bag.
70 mm Magazine LM Transfer Bag.
The 70 mm magazine UI transfer bag is made from Beta cloth, has a
capacity of three magazines, has and a flap cover to restrain them. The
magazine bag with exposed 70 mm magazines is transferred from the LM to
the CM for return to Earth.
70mm Camera Mount for 80 and 250 mm
Lens. For the purpose of photographing parallel to the CM
X-axis, the camera mount is used. It is T-shaped, the stem being
7 inches long and the bar 6 inches. The stem inserts into a socket
mount along the right or left side of the hatch frame, marked EHC MOUNT
ATTACH (80 MM/250 MM LENS, approximately 7 inches from the TV socket
mount. The T-bar portion has two quick couplings (lower and upper) that
attach to the camera. The lower quick coupling is for use of the camera
with the 250 mm lens and will align the camera parallel with the
X-axis. The upper quick coupling is for use of the camera with the 80
mm lens and is pitched upward 12±2° from the CM X-axis during
pre-launch alignment to give the camera an unobstructed view. The
couplings are labelled on the back of the mount.
To use the mount, the 70mm camera is assembled, adjusted and set. The
camera can be attached to the appropriate mount quick coupling by
sliding it to the stop and locking by rotating the (flag) lever 90
degrees. Failure to position the camera all the way to the stop before
locking may result in the window aperture obstructing the camera view.
The stem is inserted into the socket mount near the hatch frame until
the latches snap in. The intervalometer cable is then attached.
The camera is sighted by using the COAS and orienting the CM X-axis
toward the target. To use the 80 mm lens, the COAS elevation scale is
set to +12 degrees. The camera can be momentarily displaced (swung out
of the way) by pressing the latch levers and rotating until the latches
reseat.
Intervalometer. The
intervalometer is a remote control device for taking sequential
pictures. It is extremely useful for making a strip map (vertical
stereo strip from rendezvous window, oblique stereo strip from side
windows, etc.). Its control box is 2.5 x 2.5 x 1 inches and has an
ON/OFF switch. A 120-inch cable connects it to the camera accessory
connector. The intervalometer is preset at 20-second intervals and is
powered from the Hasselblad electric camera battery pack.
HEC Timing Cable. The
function of the HEC timing cable is to route the HEC shutter activation
signal , generated by the intervalometer, to the RHEB panel 227 which
is then routed to the PCM junction box. The HEC timing cable is 41
inches long with a 3-inch tee in the center. A large connector on one
end is labeled P1 and connects to RHEB panel 227. The tee connector is
labeled J1 and connects to the intervalorneter cable. The HEC connector
is labeled P2. When not in use, the cable is coiled, secured with a
utility strap, and stowed.
HEC Operation. During
preparation for lunar orbital photography the HEC, cable, and mount are
unstowed. SC1 INST PWR switch on panel 227 is verified OFF and HEC
cable (P1 connector) is connected. The HEC and the intervalometer are
mounted. The HEC cable (Ji) is connected to the intervalometer and the
P2 connector to the NEC battery pack. It is not necessary to turn the
panel 227 switch on. The intervalometer switch is placed to ON to begin
photography. When photography is completed, the intervalorneter switch
is turned to OFF, HEC timing cable is disassembled in reverse order,
and stowed.
Automatic Spotmeter
The spotmeter is a light meter that provides accurate exposure
information with a minimum of expended time and effort. The unit is a
completely automatic CdS reflectance light meter with a very narrow
angle of acceptance (one degree). The meter scales are automatically
rotated to indicate the correct camera shutter speed/lens aperture
values for the selected photographic subject. Brightness range is from
0.32 to 5000 foot-lamberts, with an extended range to 20,000
foot-lamberts by use of accessory neutral density filter. ASA range is
from 3 to 25,000 and the weight of meter is 1.9 pounds.
