Dome Inspection

Birds, Rust, and lack of quality electronics were big motivators in renovating the Northmoor Observatory.

It took the efforts of many volunteers, years of fundraising, and member support to finally get the new dome.  Drive down Sheridan Rd. and you can see the shiny, new dome.  What a Glorious site it is!

The old dome was 9,000 lbs of steel. It was operated by pulleys and man power. The new aluminum-clad dome is 20 feet, 6 inches in diameter and weighs 4400 pounds with an entirely mechanical door mechanism.
