... 1/76 = 1.3x10-2 The above telescope could resolve a 10p coin (2.4cm diameter) at 16km since the angle subtended by the coin is: 2.4x10-2 / 16x104 = 1.5x10-6 rad This gives a resolving power of: 550x10-4 / 5 = 1.1x10-7 Radio astronomy is often favoured over traditional forms of astronomy since: Obs ...

Proof: Draw EF parallel to AC to meet BC at F , and draw EC. Since point E is on the hyperbola we have (by Apo ...

... The magnifying power = (focal length of objective) / (focal length of eyepiece); both focal lengths must be in the same length units. A rough rule for the maximum magnification to use on your telescope is 20 × D to 24 × D, where the objective diameter D is measured in centimeters. So an observer wit ...

Line up your right thumb and forefinger with an upper mark on the wall and then your left thumb and forefinger with the lower mark. If the marks on the ...

... Read the sextant by first reading the line on the arc limb of the sextant (Figure 2). Read the number below the line or arrow. Add the additional lines up to the line. The illustration shows a reading of 65° and a fraction. Then read the drum against the zero (0) of the vernier scale. The illustrati ...

... I selected the observation at GMT 23:24:00, OLD 51°43.4′ as the data average, as most of the reasonable regression lines go pretty much through that point. (I also cheated, and did a little side calculation unfairly using the known GMT and Longitude. I found that this observation was very good, only ...
