Awesome! - Coda and Luke are the best! This was an amazing experience and we learned a ton. The night sky with just our naked eye was awesome but gazing through the telescopes and learning about nebulas, galaxies, planets and stars was really incredible. We had a really nice time.

Great experience and awesome staff - The staff are very knowledgeable and friendly. I learned a lot about the stars and planets. Our teen age boys had a great time looking through the multiple telescopes that the staff pointed at various stars and planets. I would highly recommend doing this tour.

Boulder AstroTour - This was amazing we seen a twinkling star in the telescope that was simply magnificent! It pales in comparison to seeing Jupiter and Saturn though so clearly! Very knowledgeable guide that helped us understand and simplify everything! No regrets, definitely 10/10 would recommend and will do again when I’m in the area.

Fun and Educational - This stargazing tour was so much fun and educational. Luke is a wealth of celestial knowledge. We could have stayed far after the tour ended to talk and learn more. Definitely a must-do when in the Denver area.

A journey in time - Luke was an amazing night sky tour guide! He's extremely knowledgeable & passionate. I liked having 4 spread out 🔭 & 1 pair of binoculars for the 17 or so people there. He reframed a couple of hours through the sky. Really neat!
