Radio astronomy from the ground up - Mark Hedley putting the finishing touches on the 4 x 4 x 4 foot hole that will contain rebar and 2.5 cubic yards of concrete to support the log-periodic antenna tower.
Thomas and Mark complete installation of the rebar and the bottom section of tower. Not to worry - Thomas was removed before the concrete pour.
\
The big pour - the tower was guyed
and levels were used to make sure it remained vertical.
Dr. Joseph Ciotti on the temporary
scaffolding - just prior to the installation of the rotator
and thrust bearing for the new antenna.
Margo - turns out parts for the
antenna mount.
Jim Sky - installing software
on one of the observatory computers.
