studmuffin Posted March 17, 2015 Share Posted March 17, 2015 Apologies for not directly LR related but does anyone know if its safe to view the eclipse on Friday 20th using a photo-chromatic welding helmet?? or indeed a dark glass welding helmet??

V8 Freak Posted March 17, 2015 Share Posted March 17, 2015 Cannot advise about welding helmets, but i can offer a simple and free solution.... Assuming you have access to a bucket or a bowl and some water. Fill the vessel of your choice and stand on a stable surface outside... Watch the eclipse in the reflection. (This method does not guarantee that the sky will be clear of clouds though....) Neil Quote Link to comment Share on other sites More sharing options...

mad_pete Posted March 17, 2015 Share Posted March 17, 2015 I think I'd say I wouldn't risk it. Would be bad to find out later the filter range is different and take eye sight damage. Quote Link to comment Share on other sites More sharing options...
steve b Posted March 17, 2015 Share Posted March 17, 2015 ...I used welding glass - 13 grade - for the full eclipse in '99 in Cornwall . It was a bit cloudy but the sun was visible and a most spectacular experience . We were on the Cheese Wring stones along with about 10,000 people up on the moor . If I won the lottery eclipse chasing would be high on the list of things to do . Got everything crossed that the cloud will stay away for this partial one cheers Steveb Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted March 17, 2015 Share Posted March 17, 2015 When I was a kid I used my dads welding helmet to watch an eclipse and again in '99 used a lens from a welding helmet to view an eclipse (during a work meeting IIRC) anyhow I'm still able to see, make of that what you will.

mickeyw Posted March 17, 2015 Share Posted March 17, 2015 When I was a kid I used my dads welding helmet to watch an eclipse and again in '99 used a lens from a welding helmet to view an eclipse (during a work meeting IIRC) anyhow I'm still able to see, make of that what you will. Yep, same here. Back in '99 I used a Speedglass helmet we had at work. My eyes still seem ok. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted March 18, 2015 Share Posted March 18, 2015 Well according to NASA who I'm guessing have some credentials in this area you should use a #14 welding lens for viewing an eclipse. Guess that answers the question. http://sunearthday.nasa.gov/2012/transit/viewing.php Quote Link to comment Share on other sites More sharing options...
UdderlyOffroad Posted March 18, 2015 Share Posted March 18, 2015 Back in '99, I used a disc out of a 3.5 floppy disc folded over into a semi circle. My eyes seem ok, and my guide dog agrees. Seriously, I don't recommend this method, but a no 14 welding glass has to be better than projection viewing. The temptation to peek with the projection method must be hard to resist.

Simon Smith Posted March 18, 2015 Share Posted March 18, 2015 I was told a #13 minimum welding glass, can't remember what mine is, but using it didn't do any harm. Quote Link to comment Share on other sites More sharing options...
zim Posted March 18, 2015 Share Posted March 18, 2015 Will an auto switching helmet work ok (speedglas) ? Or do you need a shaded lens ? G Quote Link to comment Share on other sites More sharing options...
Simon Smith Posted March 18, 2015 Share Posted March 18, 2015 My auto one doesn't work on regular sunshine, so I doubt it will for an eclipse. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted March 18, 2015 Share Posted March 18, 2015 My auto will work on a fluorescent light if you adjust the sensitivity, I guess that probably means .... maybe Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted March 18, 2015 Share Posted March 18, 2015 I've booked a left hand seat in the plane on my way home on friday, if the flight is delayed by just a few minutes I will see it from above the clouds.. it will be my luck to drop through the clouds into the Manchester rain ten minutes before it happens :-( Quote Link to comment Share on other sites More sharing options...

ballcock Posted March 18, 2015 Share Posted March 18, 2015 I was told as a youngster to smoke a piece of glass with a candle to look through. Quote Link to comment Share on other sites More sharing options...
Snagger Posted March 18, 2015 Share Posted March 18, 2015 I tried it with an old, dark welding mask a few years ago and it was good. The whole family used it in turns. But it depends on how dark your mask is. Quote Link to comment Share on other sites More sharing options...
