SUMMARY

The discussion focuses on obtaining intense star light for spectrum analysis, specifically emphasizing the Sun as the most convenient source. Participants suggest using a prism or diffraction grating to project the light onto a CCD camera for long exposure imaging. Caution is advised regarding direct observation of the Sun, recommending the use of an eclipse-grade filter to prevent eye damage. Sirius is mentioned as an alternative, though it requires longer exposure times to capture a spectrum.

PREREQUISITES
  • Understanding of spectrum analysis techniques
  • Familiarity with optical devices such as prisms and diffraction gratings
  • Knowledge of CCD camera operation and long exposure photography
  • Awareness of safety measures for solar observation
NEXT STEPS
  • Research the use of eclipse-grade filters for solar observation
  • Learn about spectrum analysis using diffraction gratings
  • Explore long exposure techniques with CCD cameras
  • Investigate the properties of Sirius for spectrum analysis
USEFUL FOR

Astronomy enthusiasts, physics students, and anyone interested in conducting spectrum analysis of celestial bodies.

i and my friend want to have spectrum of star.
i need star light with high intensity to diffract this.
unfortunately, we don't know how we can have a intense light?

do you know how we can do this?
or
in general, how can we have spectrum of light star?

The most convenient star for this purpose is our Sun.

( Prompt Blinding Danger: Do not look at Sun directly or through optics *unless* you have interposed an appropriate 'eclipse-grade' filter. Do not repeat mistake with other eye... ;-)

Beyond that, you could try Sirius, but you may need a long exposure to coax a spectrum from your prism or diffraction grating, and you are unlikely to see 'lines'...
 
The best method I THINK would be to project the light through a prism or diffraction grating and onto a CCD camera or something similar. That way you can take a long exposure of the accumulation of light and possibly see it in the picture.
