- Large telescopes often have small fields of view, i.e. it can only see a very small corner of the sky. For example, the Hubble Space Telescope (HST) Advanced Camera has a field of view that is roughly square and about 0.055 degree on a side. Calculate the angular area of the HST's field of view in square degrees.arrow_forwardLight rays from stars (including our Sun) always bend towardthe vertical direction as they pass through the Earth’satmosphere.

- The Readouts panel states that your field of view is 1.22°. That means that you are looking at a 1.22° diameter circular section of the night sky.
