For observations of comets to be of scientific value the observer should concentrate on the following: estimates of the total visual magnitude of the comet, the diameter of the coma, the degree of condensation, estimates of the length and
position angle of the tail, and detailed visual descriptions, sketches and photographs.

Caption: Comets are rendered to show the
position angle of a predicted tail based on the object's position from the Sun and Earth at the time of observation.
[PHI] is the angle between U and horizontal axis which determined by blade
position angle.
Pole figure is scanned by measuring at a fixed 2th
position angle (crystal orientation), a complete scan (spins the sample about its normal) can be performed at each specific tilt angle (Ps).Pole figure measurement is considered as an important process needs to be undertaken to get a successful characterization of the sample [9].
