اسطرلاب

نوشتار اصلی: اسطرلاب


اسطرلاب از ابزارهای قدیم نجوم و طالع‌بینی است. اسطرلاب وسیله بسیار کارآمدی در نجوم رصدی بوده و اکنون بیشتر برای کاربردهای آموزشی بکار می‌رود. این ابزار برای سنجش ارتفاع، سمت، بعد و میل خورشید و ستارگان، تعیین وقت در ساعات روز و شب، قبله و زمان طلوع و غروب آفتاب و بسیاری کاربردهای دیگر به‌کار می‌رفته‌است.
