SUMMARY

The sun's corona is a distinct outer atmosphere visible primarily during a solar eclipse or through specialized equipment such as a coronagraph. A forum participant attempted to photograph the sun using a standard camera with two layers of red cellophane, but the resulting bright areas were likely due to cloud interference and the plastic rather than the actual corona. Capturing the corona requires specific conditions or tools, emphasizing the challenges of photographing this solar feature without proper equipment.

PREREQUISITES
  • Understanding of solar phenomena, specifically solar eclipses
  • Familiarity with photographic techniques and equipment
  • Knowledge of specialized imaging tools like coronagraphs
  • Basic principles of light and optics
NEXT STEPS
  • Research the mechanics of solar eclipses and their role in observing the corona
  • Explore the functionality and types of coronagraphs used in solar imaging
  • Learn advanced photography techniques for capturing celestial events
  • Investigate the properties of solar radiation and its interaction with atmospheric conditions
USEFUL FOR

Astronomy enthusiasts, photographers interested in astrophotography, educators teaching solar science, and researchers studying solar phenomena.

I took a picture of the sun on a cloudy day with 2 layers of red cellophane on a normal camera, and edited it on the computer. There is some bright stuff around the sun in the middle. Can this possibly be the corona? :eek:

Unlikely. It's probably the clouds and the plastic making it look that way. This is the Sun's corona:

Note that you typically need an eclipse to be able to image it. Either that or specialized equipment like a coronagraph.
