Verified profile

Instrument for the direct observation of the electromagnetic radiation emitted in the visible by a determined celestial body. The spectroscope, which can be applied to the extreme eyepiece of the Cooke refractor, has a large format 5-prism dispersing system. The image of the star falls on a narrow slit, from here the light, made parallel by a collimator, first passes through a rectangle prism and then 4 prisms placed radially. The last prism, also a rectangle, inverts the optical path, returning the light to the 4 prisms, in order to increase the image of the spectrum; a lens converges light onto an eyepiece for viewing.
