6mm ASTRO BASICS STANDARD EYEPIECE (1.25" BARREL FOR ASTRONOMICAL TELESCOPE)
The magnification produced by an eyepiece depends on the optical system it is used in. For example, a 1000mm scope tube used with a 10mm eyepiece gives 1000/10 = 100x magnification. Used with a 5mm eyepiece gives 1000/5 = 200x.
