Purpose The student will explore parallax, a primary distance
... 4. To measure a parallax, you use a baseline: the distance between observation points. In the exercise above, the "baseline" is equal to the distance between the center of your eyes. Measure this distance for you and your partner. Compare these two numbers to the distances found in Step 3a. Is there ...

... The solid angle, , that an object subtends at a point is a measure of how big that object appears to an observer at that point. For instance, a small object nearby could subtend the same solid angle as a large object far away. The solid angle is proportional to the surface area, S, of a projection ...

... Writing our parallax formula in this way allows us to define a new "natural" unit for distances in astronomy: the Parallax-Second or Parsec. "A star with a parallax of 1 arcsecond has a distance of 1 Parsec." 1 parsec (pc) is equivalent to: 3.26 Light Years = 3.086x1013 km ...

Of course the beam combiner must be at 45 degrees inclination, therefore the conjugates of opposite edges of the corrector are at a different height. The conjugate surface is inclined, going from about 5.5 to about 6.5 km at the opposite edge ...
