  16. Processes Results

  17. spectroscope of making by oneself • The solar spectrum was observed with the self-made spectroscope.

  18. Examination • The solar spectrum decided to be observed taking picture of the cloud by using 16cm reflecting telescope for the observation this time. The fluorescent lamp was used as a comparison source of light. Macari was used for the analysis. • It characterizes, and absorption lines in the atmosphere are seen in any graph.

  19. The future • When the Bisei astronomical observatory was compared to what observed with the spectroscope of making by oneself, the wavelength that was able to be identified was different. I want to analyze it in detail in the future. • Moreover, it wants to observe the spectrum of the fixed star with the self-made spectroscope and to analyze it. Thank you for listening.
