Observatory Info
In 1998 our first observatory was dedicated in cooperation with the Boise Astronomical Society. They chose this site because of its limited light pollution. The 25” Obsession reflecting telescope was donated by BAS, and has provided amazing views to thousands of visitors each year. In 2023 a second observatory was built, housing a Planewave CDK700 telescope that provides imaging and remote use capabilities. The dome of the new observatory is also used as a planetarium, providing programs during the day and on cloudy nights.
Idaho Department of Parks and Recreation has identified the resource of our beautiful dark skies as a treasure to be protected. Many of our Parks and Natural spaces in Idaho are striving to increase awareness of the dangers of light pollution, to reduce their impact on the night sky environment and obtain Dark Sky certifications where appropriate through the International Dark-Sky Association. Please visit www.darksky.org for more information on this initiative and how you can make an impact!
What is light pollution?
Inappropriate or access use of artificial light.
Why is light pollution having a negative effect on Idaho?
- Plants and animals depend on daily light cycles to sustain life preserving behaviors, such as migratory patterns and feeding cycles, artificial light at night has negative and even deadly effects on many wildlife species.
- Nighttime viewing of astronomy is severely inhibited by “Sky glow” a phenomenon produced by large emissions of artificial light at night, additionally your natural night vision is briefly inhibited by white artificial light.
- Many Americans sleep in an environment that’s punctuated with some form of artificial light — whether it’s coming from an intrusive streetlight, outdoor camper lighting or flashlights. New research suggests that one night of sleep with just a moderate amount of light may have adverse effects on cardiovascular and metabolic health.
Steps you can take to preserve night sky’s while enjoying your stay at any Idaho State Campground:
- Swap outdoor lighting on your camper to an amber lensed fixture.
- Change out high admitting bulbs to bulbs emitting under 500 lumens.
- Make efforts to direct fixtures toward the ground and apply shields preventing vertical light emission.
- Keep all lighting targeted in the direction it is needed and avoid unnecessary artificial light at night whenever possible.
