Detailed Description

Dartboard widget.

It renders a target and a current position in an Alt/Az radial view.

The Dartboard is a custom widget that renders in radial coordinates the Altitude and Azimuth of two positions: the target, and the current.

Values in the radial axis range from Pi/2 radians at the center, to 0 at the outer border. Values in the angular axis start with 0 radians from the South position, and increase starting counter-clockwise up to 2*Pi radians.

The target is rendered in red, and the current position in blue.

Todo

Update to Control GUI Guidelines colors.

Implement wind direction display

Implement sky visibility according to telescope longitude, latitude and time.
