Notes from the cloudy state of Oregon, Part 1: What can a 71 mm refractor and a DSLR accomplish?

Garage Walls

Blocks were manufactured on-site with dirt that was brought in. I wasn’t there for this, hence no pictures of that process. Each block measures 16″ x 10″ x 4″, and weigh 40 lb. apiece. Placing them was a challenge standing on a ladder when the walls got high. Later building the house I bought a proper scaffold.
Surrounded by experimental (rejected) blocks is the pile of pre-mixed dirt, clay and sand, left by the block manufacturer to make mortar from. Mortar was same composition as the blocks: 95% dirt and 5% Portland cement.
