The Moonglow Technologies All Sky Cam (ASC) gives a live
video view of the entire sky day or night no matter the weather.
The camera and its lens are in a sealed glass dome with attached
cables. It has a 190 degree hemispherical field of view
giving a circular fisheye projection. The chip is a
Color 1/3" Sony Super HAD CCD II with 546 x 457 effective pixels
across the field of view. The exposure is set
automatically by the camera depending on the brightness of the
sky. It ranges from 1/100,000 second to 4 seconds.

The camera comes with a 120 Volt AC power
supply. The camera with its 1.24 mm f/2.8 three element lens
is housed in a sealed
anodized aluminum housing with a glass dome, 25 foot extension
cable, proper adapters, and cable weatherproofing sealant.
The glass dome protects the camera from rain, snow, and hail.
The accessory ASC Uploader for Windows is an optional package
designed for capturing, archive, animating, and storing
digitized images from the video feed to one's computer or for
uploading to the internet.
The All Sky Cam and optional ASC Uploader were installed at
the 3towers Observatory in December 2011. The camera was
placed on the highest point of the house roof mounted 40-inches
above the roof with a long J pole mount attached to the roof.
The cable from the camera was threaded through 1/2" conduit down
the north side of the house and through a wall conduit at the
side of the house a foot above ground level. The cable
inside the house goes to the power supply for the camera and to
the controlling computer. On the north side of the house
there is a Hawking Technology Outdoor Wireless Access Point for
data transmission between the house and the observatory, which
sits 220 feet north of the house.
