diffusing object 예문

• Diffuse interreflection is apparent when light from one diffuse object is reflected onto another.
• The visibility of diffuse objects such as star clusters and galaxies is much more strongly affected by light pollution than is that of planets and stars.
• The purpose of the catalogue was to help astronomical observers, in particular comet hunters such as himself, distinguish between permanent and transient visually diffuse objects in the sky.
• Initial inspection revealed nothing, but in late 1968 she found a June 8, 1967 exposure ( Tempel 1 had passed perihelion in January ) that held the image of an 18th magnitude diffuse object very close to where Marsden had predicted the comet to be.
