Observational Astro Flashcards
a darkened room with a small hole or lens at one side through which an image is projected onto a wall
Camera obscura
lenses in a catadioptric system
dioptrics
curved mirrors in a catadioptric system
catoptrics
lens focuses different wavelengths of light differently kind of like a prism
chromatic aberration
outer parts of a lens do not bring light rays into the same focus as the central part
spherical aberration
Largest refractor located where
Yerkes observatory
aberration inherent to certain optical designs or due to imperfection in the lens or other components that results in off-axis point sources such as stars appearing distorted
coma effect
mirror of a cassegrain telescope
parabolic
mirror of a Ritchey-Chretien telescope
hyperbolic
a cassegrain, but with a hyperbolic primary instead of parabolic
Ritchey-Chretien telescope
primary mirror type of schmidt telescope
spheroidal
a further series of mirrors outside the telescope directs the light into an environmentally controlled laboratory
coude room
dark nebula in orion molecular cloud complex that looks like a horse head
Horsehead nebula
a feature of the eagle nebula in the constellation serpens
