AstroTours.org Boulder Astronomy Tour

AstroTours.org

AstroTours.org describes the Boulder experience as “a guided night tour” using high-powered telescopes with a professional astronomer.^[2]

The operator says tours begin around sunset, last about two hours and meet at Boulder Valley Ranch Trailhead. The program combines several large telescopes with constellation and planet interpretation using a laser pointer. Depending on season and conditions, observing can include the Moon, planets, star clusters, nebulae and galaxies.^[2]

The Colorado Stargazing Trail guide uses Bortle 4 for the AstroTours.org observing location at Boulder Valley Ranch. That is a practical observing-site value rather than a certification, and actual sky quality can move with transparency, moonlight, snow cover and local light.^[2]

AstroTours.org also says the site is flat and drive-up with nearby parking, that no hiking is required, and that a basic pit-toilet restroom is available at the trailhead.^[2]

Booking information from the operator

Booking is required and walk-ups are not accepted. The current booking page lists the Boulder Astronomy Tour at $47 per person and says tours are offered when scheduling and weather conditions allow.^[3]
