BACKYARD OBSERVATORY

TO OBSERVE THE NIGHT SKIES, AN ASTRONOMER NEEDS AN ASTRONOMICAL OBSERVATORY.

THE TELESCOPE IS POWERFUL, BUT NOT STRONG ENOUGH TO SEE THRU A SOLID ROOF, SO THE ROOF WILL ROLL AWAY.

A CONCRETE SLAB AND A STACK OF 2X4s. READY TO GO.

BENEATH THIS CONCRETE SLAB IS A MASSIVE FOOTING FOR THE TELESCOPE BASE. WHILE EXCAVATING, I DISCOVERED AN OLD DRIVEWAY BURIED UNDER THE BACKYARD, SO I TIED THE FOOTING TO THAT SUBTERRANEAN SLAB.

THE FIRST WALL GOES UP...

...AND THE SECOND.
