Eclipse Viewing
« on: August 20, 2017, 04:07:33 PM »
Gorn, if you'll be there tomorrow there will be good eclipse viewing.  You should be able to see it pretty near 100% totality.  That will be very cool.  I might try the pinhole viewer with a box.  I did that when I was a kid and we had a partial eclipse.  It worked, but most likely I'll watch it on TV. 

I'm going to pray for healing for our country and the world during that time.  We need divine intervention at this point because there is so much hate everywhere.  Its all pure poison.  I don't know if there is anything we can do to change hearts and minds aside from prayer.

I can't listen to most media anymore.  I just view headline news, no opinion.  All of it is just sickening and has to stop.

Yeah, I am gonna do the eclipse thing also. Need to figure out the time when it occurs.   Are we going to have the clocks reset to run backwards, planes falling out of the sky and general panic?

Jo, I screwed up on the reservation. I'm back home now - we came back yesterday. Where we were was Cumberland Falls which is maybe 75 mi from the path of totality. At stores down there we saw signs saying "eclipse glasses sold out."

Here in Cincinnati the eclipse allegedly starts at 12:30 and the highest coverage is at 1:30. We are at the 90% totality level. For you on the east coast, Unix, probably 1/2 hour earlier.

I intend to take direct pictures of the sun with my digicam.

I did this on short notice to protest the lens and my eyes. I had some old glass neutral density filters for a camera I don't use any more. I used a candle flame to put a layer of soot on one filter. Optically it's decent. I originally sooted both sides of the filter and the sun is blacked out. I wiped the soot off one side (mistakes with this method are easy to correct!) and I was then able to see the sun as an orange disk. I will just hold it in front of the camera lens to take pictures.

The sooted filter technique is probably the best I can do anyway without investing $50+ in a photographic sun filter I won't use again ever.

My guess is light levels here will be at almost sunset level when it's at highest coverage.

We had several major eclipses when I was in my early teens. Most uneducated normies don't know that a pinhole is the original camera lens. I remember using a pinhole back then which works really well except that achieving enough darkness on the projection surface to see the sun well is kind of tricky.

Also when the eclipse is underway the sun showing through the leaves of trees casts shadows on the ground that look like little scallops, again a sort of image of the sun being focused by the gaps between leaves.

I did not see anything.  Nothing in DC area.
