It will help prevent stray light from reaching your lens, a bit like shading your eyes from bright light with your hand. However, you might find that your lens hood won't fit if you've attached a filter to your lens. In this case, try shielding your lens ...

Stray Light Analysis of High Resolution Camera for a Low-Earth

In optical astronomy, stray light from sky glow can limit the ability to detect faint objects. In this sense stray light is light from other sources that is focused to the same place as the faint object. Stray light is a major issue in the design of a coronagraph, used for observing the Sun's corona. See more Stray light is light in an optical system, which was not intended in the design. The light may be from the intended source, but follow paths other than intended, or it may be from a source other than the intended source. This light … See more There are many sources of stray light. For example: • Ghost orders in diffraction gratings. These can be caused by periodic variations in the spacing of grooves in ruled gratings, for instance. • Light scattered towards a telescope from … See more Monochromatic light Optical measuring instruments that work with monochromatic light, such as spectrophotometers, define stray light as light in the system at wavelengths (colors) other than the one intended.
