Board member, Tom Traub, used the 5″ Takahashi refractor telescope to capture the total lunar eclipse of Full Blood Red Flower Super Moon on May 15, 2022. A super moon is when it’s within 90% of its closest point to Earth. The red color of a blood moon is caused by the diffusion of the sun’s light into the shadow cast by the Earth.

Upcoming presentations in the Observatory Lecture Series.

We encourage you to come to the observatory to meet our speakers either in-person or virtually on our high-resolution, conference screen and join in our always lively Q&A after presentations. Later, if the weather cooperates, we offer tours and viewing opportunities. Click on the image for more info. You can view past lectures in our video library.
