Assuming that this velocity is distributed in accordance with the Rayleigh law, it is shown that the corresponding available sight distance (ASD) treated as a non-random function of the random impact velocity f
Coma - stars near the edge of the field look elongated, like comets, while those in the center are sharp points of light. In addition, all reflectors are subject to some light loss, for two reasons: First, the secondary mirror obstructs some of the light coming into the telescope; second...
