	8 of 8. For higher magnification and wider fields of view, AAI purchased two premium Hyperion 68° Field of View eyepieces. These are the 13 mm and 21 mm eyepieces. 13 mm = 154x magnification and 0.4 degree of sky field of view (smaller than the full moon). 21 mm = 95x magnification and 0.7 degrees of sky (slightly larger than the full moon).
