- In astrophotography, your focal length is your focal length. A 270mm FL lens is just that, regardless of the sensor size. Sensor size does affect field of view and the relationship is simple - it's linear. In other words, if one sensor is half as wide as another sensor, it will have half the field of view. -Dan

- A 200-mm (8-inch) telescope with a 2,000-mm focal length has a focal ratio of f/10. By contrast a 200-mm astrograph (a telescope designed for astrophotography) that has a focal length of 400 mm will have a focal ratio of f/2. Both telescopes collect the same amount of light, but the latter produces a much brighter image of your target.
