The Eastern Missouri Dark Sky Observers (EMDSO), in coordination with Cedar Creek in New Haven, Missouri, have been working to reinstall the Big Blue 30 inch telescope in an accessable location to better utilize it as an education tool in teaching and sharing our love of astronomy. Cedar Creek offered a unique partnership to provide EMDSO with a secure facility to house and use the observatory, and to provide Cedar Creek with another activity and resource for their guests.

The original 30" observatory was dismantled and as much material salvaged as possible.

Improvements were made to the original design to provide for better security, appearance, and useability. The new site is handicap accessible, and allows handicap observing with a video eyepiece.

The now completed observatory is used for outreach programs to the general public and is available to Cedar Creek as an extension to their fantastic property for their overnight guests.
