We have a second observatory in Southwestern Utah dedicated entirely to research operations! This photo was taken this morning as part of ongoing upgrades and renovation work. We're now able to see the Milky Way in dark locations after midnight at this time of the year!

Our April Schedule for this month!

While the eclipse was a bust, we do have some exciting news! This Wednesday is the first Summer Schedule Star Party! Meaning we will be open until 11:00pm. We'll soon have solar observations available at the start of star parties again!

Our final star party of February is tonight! Because of the Lunar Eclipse, here's the schedule for March. We'll host the Lunar Eclipse Star Party if the weather holds out. Keep posted on this page, and we'll provide updates on if we're still good to go for it. Currently, the weather is looking like it might happen!

We have made the decision to cancel our Star Party for the Lunar Eclipse this Tuesday morning. It is expected to be overcast and possibly some rain at our location. We recommend that anyone attempting to see the eclipse travel elsewhere.
