The ‘Eyepiece Gizmo’ allow members to determine important information relating to a given telescope and eyepiece configuration, including FOV (in arc minutes), Magnification and Exit Pupil. ArtdeCiel.com has on online database of hundreds of telescopes and eyepiece combinations. You simply use the pull down menus to find your telescope and eyepiece, and then confirm your selection. The ‘Eyepiece Gizmo’ automatically enters the appropriate parameters. Just press the ‘Calculate’ button and the results are displayed – hey presto! If they are not there simply select the ‘other’ option, and enter the appropriate parameters, and then press the calculate button. Eyepiece Set Eyepiece Calculator 'Gizmo' 1. Select Eyepiece 2.
