Description
This exceptional Celestron 19mm Luminos ultra wide field 2″ eyepiece uses six optical elements for optimized performance across a very wide and flat 82 field of view. A 10″ f/4.5 Dobsonian reflector will have a full 1.36 field at 60x with this eyepiece, large enough to hold all of the Pleiades in a single field. A 4″ f/8 refractor will have a 1.91 field at 43x, nearly four times the diameter of the full Moon. The calculator below will show you how wide a field you can expect with your particular telescope.
This 19mm Celestron Luminos is designed to have minimal field curvature. This makes it particularly well-suited for use with flat field telescopes such as Celestron EdgeHD and Meade Advanced Coma-Free flat field catadioptric scopes and refractors with field flatteners.
