| An excellent premium-quality low power wide field 2” eyepiece for the serious deep space explorer. The calculator below will show you just how wide the field will be with your particular telescope. For example, it will give you a 0.92 degree field at 74x with a big 17.5” f/4.5 Dobsonian. That’s almost two lunar diameters and is ideal for observing large emission and reflection nebulas and nebula remnants. While it’s particularly well-suited for use with Dobsonians (it provides a huge 6mm exit pupil for rich field observing on an f/4.5 scope), it can provide “picture window onto space” images with any telescope type that can use a 2” eyepiece. With 16mm of usable eye relief, the 27mm Panoptic can be used by eyeglass wearers with almost no vignetting of the field of view. The 27mm Panoptic would be a welcome addition to any serious eyepiece collection. It weighs a substantial 18 ounces, so you may have to do a little scope rebalancing when you use it with some low friction Dobsonians. |
