Due to space restrictions and volunteer availability, we have limited opportunities. Astronomy Nights are extremely popular, and we are currently sold out until March 2026. Because of this, we have a new system in place that will allow for more opportunities for the public to gain access to the limited reservations:
We will no longer allow tickets to be reserved months and years in advance. Moving forward, we will only release 70% (14 of 20) of the bookable slots 60 days ahead of Astronomy Night. We will release the remaining six slots at the beginning of the month of the event. You cannot view or reserve any Astronomy Nights more than 60 days from today.
Additionally, we have created a new Saturday Team of volunteers. We block out Saturday evenings for special private group and DAS member events. At the beginning of each month, any Saturday nights that have still not been reserved will be opened up for additional Astronomy Nights, and 20 tickets for each available Saturday time slot will be released at the beginning of the month.
Finally, any last-minute cancellations that open up new ticket availability will be announced on our Facebook, Twitter, and Bluesky accounts.
You can always watch the reservations page for any last-minute openings. You will be able to see all dates coming up in the next 60 days. Astronomy Night dates will only be on Tuesdays, Thursdays, and Saturdays. Gray boxes are already sold out; green boxes indicate at least one available ticket.
At this time, we do not offer a waiting list. It is difficult to maintain with volunteers and would be hundreds of guests long.

We also host a FREE mini-star party at sundown on the south lawn of the University of Denver’s Historic Chamberlin Observatory every month. Weather permitting, look through the observatory’s 20-inch Alvan Clark-Saegmuller refractor telescope and meet fellow amateur stargazers with telescopes on the lawn out front. Ask the experts there about their equipment, or bring your own if you have questions about how it works and what to look at.
You can check our Events Calendar for the next Saturday Open House this month.
Anywhere far away from city lights is best. Earth and Sky maintains a list of crowdsourced locations recommended for sky viewing.
