Wind chill is virtually eliminated, and dew formation is significantly reduced. Leakproof, waterproof and weatherproof to protect you and your equipment. The light from a computer screen, even without a red filter, is screened from outside observers. Two screened and zippered windows can be opened partially or completely for temperature stabilization and airflow control. Extra windows also available.
Reflective fabric keeps interior cooler during the hottest days, and warmer during cold weather.
Plenty of room for you, your telescope, your equipment, and a friend or three. Three-year guarantee on materials and workmanship. The same durable and weather-resistant cover material, except with a blue interior and a very light pearl exterior, for completely blocking all exterior light pollution. At a dark site, the visual observer can maintain extremely dark-adapted eyes, but without a claustrophobic black interior. The interior will also be somewhat warmer - ideal for colder climates.
