Photographic fakery The image represents a falling soldier at the time of his death in the Spanish Civil War. He was twisting towards the ground as his gun fell from his hands. The photographer took this photo 35 miles away from the town of Espejo as suggested by a Spanish researcher called Jose Manuel Susperregui. The staging of the image was very good in that it showed very little difference with the actual image at that particular time. In my view, a person serving any military forces should be dressed in a combat uniform.

In addition, how could a dying person from gunshot throw his laden hand in the opposite direction that the bullet came from? The image shows an open battlefield. If the soldier was shot from the front, how comes he never saw the attacker or even hear the creaking sound from the firing gun? Anyway, the picture is clear and the man has the heights of many Spanish people. 2. The focal length (f) of the HSD, given the diameter of the mirror (D) =2. 4m and the f-number (N) =24, is 24×2.4m=57.6m.3. The diameter of the pupil is 7 mm.

, the diameter of the HST mirror is 2.4 m. using the HST to view into the sky at night, the HST gathers more light than the eye. If the eye gathers say, x lumens the HST gathers x×2400/7 lumens. This implies that the HST gathers x×2393/7 lumens more light.4. The Hubble Space Telescope of a Ritchey-Chretien design, thought of as a Cassegrain has a concave secondary mirror.
