Brent, #14 welders' shade is _barely_ in the safe zone, physiologically speaking. It's been carefully measured. #12 might "feel" OK to look through, but dangerous amounts of IR are getting through. Retinas don't register pain. http://www.transitofvenus.org/june2012/eye-safety/280-viewing-the-transit-ey...

Best is #14. I have a couple I plan to use this weekend. I usually keep one in my truck and one in my car. Many sunspots are naked eye visible. ________________________________ From: "jcarman6@q.com" <jcarman6@q.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Friday, May 18, 2012 1:04 PM Subject: [Utah-astronomy] DeLoy Thanks for the announcement Seth. T ried to contact her yesterday about the glasses at the planetarium, but we couldn't hook up. T old her to get over to the Planetarium asap this morning. S uspect she's missed the boat, but waiting to hear from her . She might have got there around noon. It gets INCREDIBLY frustrating to have people decide they want to participate at the last minute. I'm delighted they want to go . W asn't planning on taking the C-8 with the mylar filter, but will now. I have a 3" finder scope with a #14 welder's glass ready to go. That was all I was going to take (well the camera and a tripod, of course). Hmm after loading all that, hope there's room for the chairs lol. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Send messages to the list to Utah-Astronomy@mailman.xmission.com The Utah-Astronomy mailing list is not affiliated with any astronomy club.
