Assignment:

1) Estimate how many photons per second will your eye detect from a 5th magnitude star seen through a filter that transmits light between 5000 and 6000 angstroms (roughly the V band)? Assume that your eye pupil has a diameter of 5 mm.

2) A star has an apparent magnitude of mV=10 and an absolute magnitude of MV=0. What is its distance? Is this star more or less luminous than the sun? By how much?
