Welcome to the Custer Institute

Weather permitting, Saturday Night Observing is from 8pm to midnight
where vounteer Staff provide guided tours of the sky.
Clouds, fog, rain, and full moon nights are not good nights for observing,
but are good nights for indoor projects and maintainence.

A full moon is very birght and makes it difficult to see much else.
Generally, the less moon, the better for oserving deep sky objects.
Can you find all the Appolo Landing Sites on the full moon?

Check the moon-phase calendar here.

Doors open at 7pm
Weather permitting, observing until Midnight.

We depend on your generous donations
which are gratefully Accepted.
