Sky Views



Sky Map:
The Sky Map shows the Entire Sky as Viewed (South) from the Silver Acorn Weather Station's Location. The Limiting Magnitude is the Faintest Apparent Magnitude of a celestial body and frequently refers to the Faintest Stars that can be seen with the unaided eye on a clear Moonless night. On the 'Sky Map', the Limiting Magnitude is set to 4.0 which corresponds to roughly 250 visible Stars
Horizon Views:
Horizon Views is showing the Stars above the Horizon as seen from a Specified Observing Site (Silver Acorn Weather Station). The Viewing Direction (azimuth) is set to 180° (SOUTH) as Cardinal Point on the Compass with a Field of View of 75°
Observing Site:
The Sky View Depends on where you're standing on the Earth. The Sky Map uses the Latitude and Longitude Coordinates of the Weather Station's Location of the El Gheko Neighborhood Weather Station in Tucson, AZ USA. Coordinates:  32°13' North and 110°50' West
Viewpoint:
The azimuth Specifies the Direction of looking towards the Horizon. The Viewpoints on the Sky Map are set to South (180°) with a Field of View of 45° in addition there are views to the North (0° or 360° depending on your point of view), East (90°) and West (270°).

HORIZON VIEW (FOV=75°)

Azimuth 180° (South) Field of View 60°

An azimuth is the measurement of the position of a star in the sky. The star is the point of interest, the reference plane is the horizon, and the reference vector points to the North or South. The Azimuth is the angle between the North or South vector and the perpendicular projection of the star down onto the horizon.

Azimuth 0° (North) Field of View 60°


Azimuth 90° (East) Field of View 60°

Azimuth 270° (West) Field of View 60°

The ecliptic is defined as the plane containing the Earth's orbit. With respect to that plane, the other orbits are inclined and thus, in the course of each revolution the planets rise above and fall below the plane of the ecliptic. The portion of the orbit above the plane of the ecliptic is drawn in blue, the portion below in green.
