    Versatile movie and still camera as flown on all the manned moonlanding missions, serial no. 0001

    Apollo Moon Missions: Prototype of the J. A. Maurer 16mm Data Acquisition Camera with Archive of Related Photos. An early prototype of the legendary "DAC" as carried on Gemini and both the Lunar Module and Command Module of all the Apollo lunar missions. All of the movie footage we have of the lunar missions and many of the stills (including the ones of Neil Armstrong on the moon) were made with a Maurer 16mm of which this is a prototype. This is the type of camera that was mounted at the window next to the Lunar Module Pilot on the lunar landings. During Apollo 11, the Maurer DAC recorded the descent to the lunar surface for landing, Armstrong's descent down the ladder, and eighty-six minutes of the lunar EVA (see YouTube videos below). These 16mm color cameras used film magazines that held about 130 feet of color film which, at the standard 24 fps would have only provided three+ minutes. Because they allowed frame rates as low as 1 fps which is what was used for the moonwalk footage, the time could be extended tremendously. After Apollo 11, the DACs were taken outside of the LM: on Apollo 12 one was mounted on the Lunar Hand Tool Carrier; Apollo 14 had one mounted on the Modularized Equipment Transport cart; on Apollos 15-17, they were mounted on the Lunar Rover. Another of these was also always mounted in the Command Module to take movies of docking procedures, etc.

    This rare, sturdily-constructed camera measures 7.75" x 4.75" x 2.25" overall and weighs 2 lbs. 6 oz. The information engraved on the front next to the shutter release reads: "Model No/ 296-200-000/ Serial No./ 0001" with a "Maurer 16mm" logo above the lens. On the removable lens barrel is engraved: "P. Angénieux Paris F. 10 1:1.8 Retrofocus R21 No. 1136321/ Lens Made in France" and there are aperture settings from f1.8 to f16. Two four pin electrical connectors are found on the bottom with a Mode selection switch on top with five positions: "Time Exp", "Single", "Test", "1 FPS", and "6 FPS". An unmarked four-position switch at top right is likely for shutter speed selection. Metal "J. A. Maurer, Inc." plates are attached to each side and there is a mounting bracket on the left. The film magazine is removable by means of a latch on the back. An absolutely indispensable piece of equipment for the Gemini and Apollo astronauts. This one is certainly unique being from the company's archives. A great opportunity for the Space Photography enthusiast. Fine with normal signs of use and testing.

    Early models of these Maurer 16mm cameras, as well as 70mm cameras they manufactured, flew on the Gemini missions. Included with this lot are twenty+ 8" x 10" original NASA color photos, all with the desirable "red numbers," that were taken with Maurer cameras. All excellent. Also with it are additional photos and archival items from the Maurer company files.

    Also included with this lot is a 16" x 20" color photo of Richard Gordon holding a Maurer DAC. On the bottom of the mat, he has signed: "To Dan Ehrlich-/ Very best wishes & many thanks!/ Dick Gordon". Mat damaged, photo very good.

    Additionally with the lot: a group of seven modern 8.5" x 11" glossy prints from NASA's archives of these Maurer 16mm cameras being used on or in preparation for various Apollo missions. Includes an image of the Maurer mounted in Apollo 11.

    More Information: 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.

    16mm Camera and Accessories
    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 'film 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 spacecraft's 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.
