Slender Evidence of a Solar Eclipse

As followers of the Great Eclipse of 2017 already know, the safest way to see an image of an eclipse is to use a pinhole on a sheet of paper or cardboard to project the little crescent of sunlight. Raleigh had only a partial eclipse, so you get only a sliver. The pinhole was made with a ballpoint pen in a hurry. The aperture was not perfectly circular, so the crescent sun is too short. Still, I am proud to have produced optics on a slender budget.

Nicely done, Larry! And a wonderful memento for you!

My brother used binoculars, he lives on Vancouver Island. He sent me some pictures which I posted on FB last night. I think you did well with the eclipse. We followed some on CNN when it 'hit' Oregon.
Larry Bliss: It's good to make astronomy a family affair...
I love the variation on the theme, Larry!
Larry Bliss: thank you Ginnie...

I like this very much Larry, especially with your story of an emergency device to see the partial eclipse. Yes, I think it's great simply projected on this brick wall.
Larry Bliss: It doesn't take much to amaze me...
Very good Larry. One of the better pictures of the event
Larry Bliss: Thank you Bill... but I still want a fancy telescope for my birthday... smile
How great that you were that resourceful!
Larry Bliss: Many decades ago I was a Boy Scout...
