The Texas Astronomical Society of Dallas wishes to partner and participate with individuals, groups, schools, towns, and all forms of organizations to celebrate the 2024 total solar eclipse. This majestic celestial event will be, for many, a once-in-a-lifetime opportunity that is certain to inspire wonder about our place in the universe. We in North Texas are fortunate to sit on the path of totality, and with this opportunity we will provide education to whoever desires it.

Within this outreach kit, you will find in-depth information and ample resources to help you have a successful total solar eclipse viewing.

If you have questions about any of the content provided, or require further information regarding the science of eclipses, safety, or planned events, please feel free to reach out to us at, and follow us on Facebook and Instagram to stay up to date on our club’s events, news, and general membership meetings. And of course you can become a member of TAS at

Eclipse Safety

  • Always inspect your solar filter before use; if scratched, punctured, torn, or otherwise damaged, discard it. Read and follow any instructions printed on or packaged with the filter.
  • Only use eclipse glasses marked as ISO 12312-2 and only from a reputable source. Or, #14 welder's glass.
  • Always supervise children using solar filters.
  • If you normally wear eyeglasses, keep them on. Put your eclipse glasses over them (on top), or hold your handheld solar viewer in front of them.
  • Stand still and look down or away from the sun before applying the eclipse glasses.Cover your eyes with your eclipse glasses or solar viewer before looking up at the bright Sun. To remove the solar eclipse glasses after looking at the Sun, turn away and remove your filter — do not remove it while looking at the Sun.
  • Do not look at the un-eclipsed, partially eclipsed, or annularly eclipsed Sun through an unfiltered camera, telescope, binoculars, or other optical device. Do not put eclipse glasses behind optical equipment such as binoculars or a telescope.
  • Do not look at the sun through the following: x-ray film, old camera negatives, ordinary sunglasses no matter how dark or UV protected, CDs, DVDs, etc.
    • Similarly, do not look at the Sun through an unfiltered camera, telescope, binoculars, or any other optical device while using your eclipse glasses or handheld solar viewer in front of your eyes — the concentrated solar rays could damage the filter and enter your eyes, causing serious injury.
  • Seek expert advice from an astronomer before using a solar filter with a camera, telescope, binoculars, or any other optical device; note that solar filters must be attached to the front of any telescope, binoculars, camera lens, or other optics, not the back.
  • After you see the first "diamond ring" and during totality (C2), remove the eclipse glasses. And, be sure to reapply the eclipse glasses before totality ends (C3) after the second "diamond ring". The sunlight during a solar eclipse is not worse than normal sunlight. Same thing with a lunar eclipse at night. A lunar eclipse is not harmful at all. Be aware that 1% of the sun is 10,000 times brighter than a full moon (Michael Bakich).
  • Some older department store telescopes came with a glass solar filter to add to an eyepiece or to the back of the telescope. Those must never be used. They might crack under the heat and allow harmful light through and cause permanent damage to the retina.
