“Astronomy compels the soul to look upwards and leads us from this world to another” - Plato (428 BC - 348 BC)
Students are encouraged to think of themselves as ancient astronomers.

Star Trail Photos
• camera pointed at celestial pole
• use the star trail photo to determine latitude
• length of photographic exposure
• time of shutter opening/closure
• use of R.A. & declination for star positions
