Welcome to the Custer Institute

Weather permitting, Saturday Night Observing is from 8pm to midnight
where volunteer 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 maintenance.

Generally, the less "full" the moon is, (that is, the darker the sky)
the better it is for observing deep sky objects such as nebulae and galaxies.
Can you find all the Apollo 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.

It ain't necessarily so!: A Winter Solstice Tale, B. Farrell.
The talk concerns the winter solstice and the many aspects of it that we think we know but are just not true, It Ainít Necessarily So. Mr Farrell will demonstrate how the earliest sunset occurs around a week before and the latest sunrise around a week after the solstice. Using models and interactive computer models he will show the movements of the earth at this time of year. After all, "the Solstice is the real Reason For The Season!"
