| An excellent and physically-impressive premium-quality low power wide field 2" eyepiece for the serious deep space explorer. You can use the calculator below to see just how wide the field will be with your particular scope. For example, it will give you a 1.19 degree field at 57x with a big 17.5" f/4.5 Dobsonian. That’s well over two lunar diameters and is ideal for observing large emission and reflection nebulas and nebula remnants. While it’s particularly well-suited for Dobsonian use, it can provide “picture window onto space" images with any telescope type that can use a 2" eyepiece. The 35mm Panoptic provides a huge 7.8mm exit pupil on an f/4.5 scope, which may actually waste some of an f/4.5 scope’s light-gathering capacity if your eye can’t dilate enough to take in such a large exit pupil. Focal ratios of f/5 (a 7mm exit pupil) and longer may benefit the most from this very big and visually-impressive eyepiece. With a huge 28mm of usable eye relief, the 35mm Panoptic can be used by eyeglass wearers with no vignetting of the field. The 35mm Panoptic would be a welcome addition to any serious eyepiece collection. It weighs a hefty 28 ounces, so you may have to do some scope rebalancing when you use it with some low friction Dobsonians.
