We carry the Orion full-aperture glass filters. For a 10" Dob it would be about $160. If you've got that kind of money burning a hole in your pocket, more power to you and you'll love it. BUT, I question the need for that much of a filter. A far less expensive and probably just as useful solar filter could be made using a 4" off-center hole covered with Baader Astro Solar Safety film in a cardboard disk over your scope. I know there's been plenty of discussion on this topic in these messages. We've just sold out of the full-aperture glass filters for 8" and 10" Dobs, but Orion tells us they'll have more here in plenty of time for the eclipse. If I had a nice 10" Dob, I'd get the Baader filter and make an off-center "solar filter dust cover" for my scope. I suspect there's no shortage of people here who can tell you about how to make one.

Yes, you can get them for less online but you have to buy them in bulk as Wayne did. We bought a lot of them in anticipation of public interest in both the eclipse and the transit of Venus on 6/5. People with good vision should be able to see Venus on the Sun with just the solar eclipse glasses. It'll be about the size of a medium sunspot. The $1.95 eclipse glasses work great - they're made specifically for looking at the Sun. We also sell glass solar filters for telescopes and binoculars - the same items you get online from Orion. Also, you could go to a welding supply company and buy Grade #14 welder's helmet glass filter plate. It must be Grade 14 (they call it "shade 14") or higher to be safe. Costs about $4 for a 4" x 5" plate. The Sun is a lovely shade of green through these. No, you can't combine two #7's to achieve the same result. Doesn't work that way.

They are about a dollar each which worries me somehow. While I don't want to pay more than is necessary, I am wondering - really? - can I trust my eyes to be safe for a dollar?
