A 28mm 2" eyepiece is included to get you started. Standard 1.25" eyepieces are also compatible. 

    Constructed from sturdy rolled steel with cast-aluminium aperture and eyepiece cells makes the Skywatcher Black Diamond ED 100mm Refractor OTA highly durable. Quick release mounting rings are included, allowing the optical tube to be attached to any Skywatcher mount.
