Collimation in azimuth refers to the alignment of a telescope or observational instrument so that its optical axis is parallel to the true north direction. This process ensures that the instrument can accurately measure the azimuth angles of celestial objects. Proper collimation is essential for precise navigation and astronomical observations, as it minimizes errors caused by misalignment. In practice, this often involves adjusting the telescope's optics to ensure that the image is centered and sharp when aimed at known reference points.
A BACK AZIMUTH IS A PROJECTION OF THE AZIMUTH FROM THE ORIGIN TO THE OPPOSITE SIDE OF THE AZIMUTH CIRCLE. i.e. THERE ARE 360 DEGREES IN AN AZIMUTH CIRCLE, THUS THE OPPOSITE DIRECTION IS 180 DEGREES.
Astronomical azimuth is measured from true north, while geodetic azimuth is measured from the north-south line of a geodetic datum. In other words, astronomical azimuth uses the Earth's axis as reference, while geodetic azimuth is corrected for the Earth's shape and gravity. This difference leads to variations in azimuth readings, especially over long distances.
The point from where an azimuth originates is the center of an imaginary circle.
The azimuth of a star is measured as the horizontal angle from a reference point, typically measured in degrees clockwise from north. It is often determined using a compass or an azimuth circle in astronomy.
The azimuth of Capricorn is around 270 degrees. This means it is located in the southern part of the sky, towards the west.
The height of collimation is the height of the line of sight. It is the vertical distance of the horizontal plane through a telescope.
A BACK AZIMUTH IS A PROJECTION OF THE AZIMUTH FROM THE ORIGIN TO THE OPPOSITE SIDE OF THE AZIMUTH CIRCLE. i.e. THERE ARE 360 DEGREES IN AN AZIMUTH CIRCLE, THUS THE OPPOSITE DIRECTION IS 180 DEGREES.
An azimuth thruster is an engine and ship's propeller in a pod which is azimuth adjustable.
To convert a magnetic azimuth to grid azimuth, subtract G-M angle.” If you have a magnetic azimuth of 270 degrees, and the G-M angle is 8 degrees, your grid azimuth will be 262 degrees.

Collimation Error: Collimation error occurs when the collimation axis is not truly horizontal when the instrument is level. The effect is illustrated in the sketch below, where the collimation axis is tilted with respect to the horizontal by an angle α: Figure ( ) In this particular example, the effect is to read too high on the staff. For a typical collimation error of 20", over a sight length of 50m the effect is 5mm. If the sight lengths for back sight and foresight are equal, the linear effect is the same for both readings. When the height difference is calculated, this effect cancels: δh = (b + s. α) - (f + s. α) = b - f That is, the effect of the collimation error is eliminated if sight lengths are kept equal.
The back azimuth is the direction opposite to a given azimuth. To calculate the back azimuth of 179 degrees, you would add 180 degrees. Since 179 + 180 equals 359 degrees, the back azimuth of 179 degrees is 359 degrees.
