ment knobs moves the strike of the bullet 3 inches (7.62 cm) at 150 meters. The sight reticle is designed for use as a passive (without power) reticle under high light level conditions. However, provisions have been made to permit "charging'' of the reticle to compensate for low light level conditions. (A black line reticle ((5), fig. 3) wil lreplace the bead-type reticle in the very near future.)
(5) The power supply system for the Starlight Scope consists of a power supply housing (fig. 2), a 6.75-volt mercury cell battery, a high voltage oscillator, wiring, and a toggle switch. The three-position toggle switch (fig, 2) provides for sight ON (passive reticle), sight OFF, and reticle CHARGE positions. The middle position of the switch is sight OFF. The upper position of the switch is sight ON, and the lower position of the switch permits CHARGING of the reticle.
(6) The eyepiece assembly (fig. 2) mates into the rear of the main housing and is held in position by the eyepiece retaining nut. The eyepiece assembly consists of six glass elements (2 doublets, a singlet, and a window). One of the doublets and the singlet glass element are capable of forward and rearward movement by means Of the eyepiece focus ring (fig. 2). This movement enables the operator to focus the eyepiece assembly to meet individual eye requirements. A diopter scale (fig. 2) is engraved on the eyepiece assembly immediately forward of the focus ring. This diopter scale enables the operator, once he has obtained his own focal setting, to preset the eyepiece focus ring, thus eliminating the necessity for refocusing the eyepiece each time the Starlight Scope is used. The eyepiece assembly is purged in an atmosphere of dry nitrogen to prevent lens fogging. Attached to the eyepiece assembly is a rubber eyeshield (fig. 2) which protects the eye from shock caused by recoil when the weapon is fired. The rubber eye-
shield also aids in security by providing the operator with a means of coveryjg the areas around the eye, thus preventing light leaks on other areas of the face caused by the visible glow emitted from the rear of the eyepiece assembly.
Note. The Starlight Scopc may bo shipped with either a "cccuro" or "nonsecure" rubber eyeshield. Tho oy «shields are identical except the "securc" oyoshlald hoe a rubber flap over the end which must be pulled aside before the operator can view through the eyepiece. Upon removal of tho eyeshield from the eye, the flap closes and is held shut by two magnets.
(7) Installed on the underside of the main housing is the telescope mount assembly _ which provides a means of mounting the-Starlight Scope to the weapons adapter bracket (fig. 2). It is equipped with two locking knobs which are used to secure the mount assembly to the weapons adapter bracket.
(8) The image intensifier tube is located inside the main housing between the sight reticle assembly and the eyepiece assembly. It concentrates and intensifies the ambient light of the night sky to such a degree that distant objects appear as images within the Starlight Scope.
(0) The lens cap (fig. 2) mounts over the objective lens. It has three small pinholes drilled around its center to limit the amount of light entering into the Starlight Scope. This permits operation of the Starlight Scope during daylight hours for zeroing purposes.
d. Accessories. Shipped and stored in the shipping container, as accessories to the Starlight Scope, are five 6.7fi-volt mercury batteries, two sight reticle lamps, two weapons adapter brackets, three alien wrenches, a low temperature adapter assembly, a canvas carrying case, a nylon carrying x strap, and a lenB brush and lens tissue (fig. 1).
(1) The 6.76-volt mercury battery provides the power required for operation of the Starlight Scope. Five batteries are shipped with the Starlight Scope; however, four 'are spares since only one is needed for operation of the equipment.
The battery does not have a recharging capability. When its use-life lias been expended, the battery is discarded (para
(2) Even though two sight reticle lamps are shipped as accessories to the Starlight Scope, the operator is not authorized to remove and/or install lamps within the Starlight Scope. When turned on, the lamp provides the visible illumination necessary to charge the Right reticle.
(3) Two weapons adapter brackets are contained in the shipping container. One bracket is for mounting the Starlight Scope to the M14 or M14À2 rifles and one bracket permits installation of the Starlight Scope to the XMlôEl rifle. A separate weapons adapter bracket is provided for mounting the Starlight Scope to each of the other weapons listed in paragraph 4a and may be procured through normal supply channels.
(4) The three alien wrenches are the basic tools required by the operator for disassembly and assembly of the Starlight Scope and for installation of the weapons adapter brackets (saddle block for M60 machinegun excluded).
(5) The low temperature adapter assembly permits operation of the Starlight Scope during low or arctic temperatures. The low temperature adapter assembly may be assembled to the battery housing, permitting the operator to carry the battery inside the battery adapter case. The battery and battery adapter case may then be positioned inside the clothing of the operator where body heat will protect the battery against low temperatures.
Note. Somo models do not contain & Low temperature adapter assembly.
(6) The canvas carrying case affords protection and provides the operator with a means of transporting the Starlight Scope in other than the shipping container. The case has a keeper and slide assembly for attachment to the pistol or cartridge belt. A zipper is installed for closure of the case.
(7) The nylon carrying strap has adjustable loops at either end for attachment to the Starlight Scope to provide p,n additional carrying capability.
(8) A Jens brush and lens tissue are provided for cleaning the objective lens and the eye lens.
