May I treat the light from a star as a light beam?

[QUOTE="Drakkith, post: 6833464, member: 272035"] What do you mean? The star has an absolutely tiny angular diameter. Much less than its image on the sensor. If you mean to treat the beam of light as having a diameter that's the same as the physical diameter of the star, well no, you can't do that. That wouldn't make any sense in terms of optics. I don't see why you couldn't. I was under the assumption that this was exactly how light was treated normally. A 'beam' of light passing through the atmosphere and entering the aperture of the telescope. Treat the beam as being made up of rays of light or as wave fronts depending on which one is appropriate for what you're doing. [/QUOTE]
