This is one of the most popular premium-quality 1.25" low to medium power wide field eyepieces. An ED glass element provides high contrast for observing very subtle low surface brightness features in extended nebulas. While it is particularly well-suited to observing with Dobsonian reflectors and fast focal ratio refractors (it provides a big 5.3mm exit pupil for rich field observing on an f/4.5 Dobsonian), it provides "picture window onto space" images with any telescope type. This Panoptic, for example, will give you a 1.43 degree field at 48x with a 10" f/4.5 Dobsonian. This gives you over five and a half minutes of uninterrupted observing with such a scope while an object drifts from one side of the eyepiece's flat field to the other. That's plenty of time for multiple observers to look at the same object, or for you to absorb as much detail as possible, before having to reposition the scope. An excellent eyepiece for observing galaxy clusters, framing emission nebulas with the black of space, observing the nebulosity around the Pleiades, etc. The 24mm Panoptic would be a welcome addition to any serious deep space observer's eyepiece collection.
