Across
- 3. lens at the front to gather, bend, and focus light down a seated tube to an eyepiece at the rear
- 4. Science of measuring visible light in a way that matches how the human eye perceives its brightness
- 5. an imaging method where a camera sensor is placed directly at a telescope's focal plane with no eyepieces
- 7. a clear optical device that blends light rays to focus on spread them
- 9. building/ facility equipped with instruments to study space, weather, or natural phenomenas
- 10. the physical cross-section of its primary lens or mirror that intercepts incoming light or radiation
- 12. measurement and imaging technique which combines two or more waves
- 13. an optical or electronic instrument used to gather light and magnify distant objects
- 14. flash of light or rapid change of brightness produced when a material absorbs high energy ratiation, or when light passes through something like earth's atmosphere
- 15. "picture element" it is a single dot or square in a larger digital grid
Down
- 1. the process of spreading things out or the state of being scattered over an area
- 2. bending of a wave as it passes from one material into another at an angle
- 6. combination of curved and flat mirrors to gather and focus light instead of using glass lenses
- 8. light sensitive integraded circuit that converts incoming light photons into electrical charges to capture digital images
- 11. a telescope's ability to see fine details and separate two close objects as distinct points instead of a single blur
