Where to find solar filters

But totality is fleeting. In every case, the solar filter must be attached to the front of your telescope, binoculars, or camera lens. If your telescope has a small auxiliary finderscope or other aiming device, make sure that it is capped, removed, or safely filtered just like the main telescope. Solar filters provided with inexpensive telescopes, usually designed to thread into an eyepiece at the back end of the telescope, are dangerous.

You don't need astronomers to tell you that, but you do need astronomers to tell you where to get safe solar filters: from the companies listed on this page.

To do otherwise is to take unnecessary risks. If a supplier isn't listed here, that doesn't mean its products are unsafe — only that we have no knowledge of them or that we haven't confirmed that their products meet the transmission requirements of the ISO international safety standard.

For more information see our Eye Safety pages. Note 2: Jaxy doesn't sell direct to customers; they manufacture for other companies. Their solar viewers could be described as "too safe" — they block a bit more visible light than the ISO standard allows, rendering a safe but rather dim view of the Sun.

Technically, they aren't compliant with ISO , but because they are safe, and because several trustworthy vendors are selling eclipse glasses made by Jaxy, we include them here.

Other sources: What if you received eclipse glasses or a handheld solar viewer from a relative, friend, neighbor, or acquaintance? If that person is an amateur or professional astronomer — and astronomers have been handing out eclipse viewers like Halloween candy lately — they're almost certainly ISO-compliant, because astronomers get their solar filters from sources they know and trust in other words, from the ones listed on this page.
