STAR DIAGONALS ( 3 )
Star diagonals are an important accessory for viewing comfort when using refractor and SCT telescopes. Light is diverted 90 degrees into the eyepiece so you don't have to crane your neck! Two types are available: Mirror and Prism. In addition, e-Scopes® has an erect image version for correcting the image of a Refractor Telescope for terrestrial (land) use.
