Dark Texas Skies introduces cosmic adventurers to the stars with two large observatory grade reflector telescopes. Oberwerk BT-100XL-ED and BT-127XL-SD binoculars are also used to view larger celestial objects, which are mounted on top of state-of-the-art “Go-To” instruments. Whether you are a seasoned astronomer or a newcomer, you will enjoy using our equipment.
Dark Texas Skies is located at the Marathon Motel & RV Park in Marathon, TX. This establishment has been featured on Texas Country Reporter and in magazine & newspaper articles because of its many amenities and its stunning nighttime canopy of stars.
Below is a map where Dark Texas Skies meet nightly. We gather outdoors at the Visual Observatory, about 150 feet behind Room 8 of the Marathon Motel & RV Park. Admission is $10.00 for adults and children are free younger than 18 years old.
Star parties are scheduled every night of the calendar year (including holidays) if the weather permits and the date is NOT indicated by a red marker on the Moon Phase Calendar. We begin at sunset if the Moon is visible, otherwise we begin 1/2 hour after sunset.
Dark Texas Skies boasts a very dark nighttime sky. We are located in one of the darkest areas in the lower 48 contiguous United States!
track & see the ISS
Guests are notified when the International Space Station flyover occurs. The ISS usually appears very bright as it glides across the night’s sky at 17,500 mph as it orbits every 90 minutes at an average altitude of 227 nautical miles above the Earth.
The real-time NASA tracker shows where the International Space Station is right now and its path 90 minutes ago (-1.5 h) and 90 minutes ahead (+1.5 h). The dark overlay indicates where it is nighttime in the world.
