Day 2 and 3 of Night Sky Observatory build

Yesterday was the day to complete the removal of the remaining grass and to travel to three Home Depots to finally get the 16"x48" form tube (they shipped me a 10" and the 16" tubes were hard to find. Then there were the anchor bolts ... what a task that was to get them. Whew. Started digging the holes.

Today the corner footer holes for the deck were completed and the concrete poured (2 bags per hole). The dig of the pier footer hole took awhile being 18"x 38-40" deep! But it is ready for concrete pour later this weekend. Decided to build the deck first, cut the center hole for the pier and then pour concrete from the top of the deck. This way I can precisely set the footer height to be at just the right height for the pier base to be just an inch or so under the deck floor.

Temps are getting a bit steep here in Maryland, so tomorrow is gonna be a bit uncomfortable (90's).
