Lo-Tech Eclipse Lagniappe


Lagniappe / Tuesday, August 22nd, 2017

A total eclipse must be an awesome thing to experience. Here in North Texas, the occlusion was at roughly 75%. Despite the lack of totality, eclipse glasses sold out weeks before the date. I opted for lo-tech eclipse viewing. But it worked. It’s a bit of lagniappe, while Debra works on another Hildring House post.

Materials at Hand

Cardboard and shadowA hunk of cardboard, ripped from a box of something or other, with a hole poked by Phillips-head screwdriver made a basic viewer. Why a Phillips-head? Because I couldn’t find our ice pick, if we even still have an ice pick, and because it’s round. I did have to trim the fuzzy edges of the hole with the kitchen shears.

Image on concreteAs the occlusion started to show up in the image, I was disappointed in the quality of our driveway as a screen. So I went inside and grabbed a piece of printer paper.

Improved Visualization

Point of Maximum OcclusionThis picture, taken at 1:08 CST shows our maximum occlusion. You can also see the image at the edges of the cardboard (most notably at the ragged lower right-hand edge) and – my favorite – in the gap between my finger and the cardboard.

Here’s one more from a few seconds later:

Another image of the eclipseLo-tech eclipse viewing was a thing, apparently. I’ve seen some really cool images across the web of hundreds of eclipse-crescents made by everything from tree leaf shadows to a colander held above a white foam board (quite clever, that one!).

The best thing about the eclipse was that, for a few minutes, the whole country had its attention turned in the same direction, observing a natural phenomenon far, far bigger and more wonderful than any of the issues that divide us.

We all walk under the same sun.

I hope the rest of your week is peaceful, pleasant, and prosperous.
