The Revival of Amateur Spectroscopy

Description:This schematic diagram shows how a diffraction grating produces a zero-order image and a first-order spectrum. By then spectroscopy had been adopted by professional observatories in North America and Europe, which had the large-aperture telescopes needed to exploit this powerful tool. The mirror redirects sunlight onto the needle or eyepiece, which provides a sliver of light to be split by the prisms. Placing a slit at the entrance of the spectroscope will help mask degrading skylight. The focus of these lenses will usually need to be adjusted when you are recording the infrared region of the spectrum, as few lenses yield sharp images at visible and infrared wavelengths using the same setting. Today the inefficient photographic plate has been superseded by electronic CCD detectors, and professional astronomers probe the depths of the universe with huge telescopes like the meter Keck reflectors in Hawaii.
