True field equals 57.3 multiplied by 27.2 and divided by your telescope's focal length.

The 68° here is built around a maximum-diameter field stop and long eye relief in the smaller barrel size. In a 1.25-inch-only telescope the 68° 24mm is the wider true field of the two; in a 2-inch focuser the comparison changes.

The visual effect of these eyepieces with their long eye-relief and their 68° apparent field is truly a full-immersion experience. The 68° Series eyepieces come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.\u003co:p\u003e\u003c\/o:p\u003e\u003c\/span\u003e\u003c\/p\u003e  \u003cp style=\"margin:0in;margin-bottom:.0001pt;line-height:13.5pt;background:white\"\u003e\u003cspan style=\"color: rgb(34, 34, 34); font-family: Arial, sans-serif; line-height: 13.5pt;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"margin:0in;margin-bottom:.0001pt;line-height:13.5pt;background:white\"\u003e\u003cspan style=\"color: rgb(34, 34, 34); font-family: Arial, sans-serif; line-height: 13.5pt;\"\u003eProtection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled.\u003c\/span\u003e\u003c\/p\u003e  \u003cp class=\"MsoNormal\" style=\"margin-bottom:0in;margin-bottom:.0001pt;line-height: 13.5pt;background:white\"\u003e\u003cspan style=\"font-family: Arial, sans-serif; color: rgb(34, 34, 34); background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;\"\u003eArgon atoms are   larger  than that of Nitrogen and therefore they are less likely to  leak  or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters\/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components, and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally because Argon is less conductive of heat than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.\u003co:p\u003e\u003c\/o:p\u003e\u003c\/span\u003e\u003c\/p\u003e  \u003cp class=\"MsoNormal\" style=\"margin-bottom:0in;margin-bottom:.0001pt;line-height: 13.5pt;background:white\"\u003e\u003cspan style=\"font-family: Arial, sans-serif; color: rgb(34, 34, 34); background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;\"\u003e\u003co:p\u003e \u003c\/o:p\u003e\u003c\/span\u003e\u003cspan style=\"color: rgb(34, 34, 34); font-family: Arial, sans-serif; line-height: 13.5pt;\"\u003eThe sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements.

It's certainly a high quality eyepiece then, with it's broad field of view and extended eye relief ensuring that mix of comfort and practicality that can be called optimal. It's an ideal eyepiece to practice averted viewing with, as well; the wide field of view letting you look slightly to the side of faint items to see them better by allowing more sensitive parts of your eye to be what's focused towards them. And that's not all the broad field of view is good for! It also makes it easier to find objects in the night sky and keep them in your field of view for far longer without adjustment than eyepieces with lower FOV's can manage.

A 1000mm telescope gives 154x; a 1219mm Dobsonian gives 188x.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does LER mean here?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLong eye relief. The published figure is 16.8mm, which at a 6.5mm focal length is unusual — short eyepieces normally place the eye very close to the lens. It is what makes high-power observing with glasses on, or simply for long stretches, comfortable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it with glasses on?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. 16.8mm is enough for most spectacle wearers to take in the field, which is the specific problem this design sets out to solve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs 6.5mm too much magnification for my telescope?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt depends on aperture and on the night. As a rule of thumb the atmosphere supports around twice the aperture in millimetres as a maximum useful magnification, so a 150mm telescope tops out near 300x on its best nights. At 6.5mm you reach 231x in a 1500mm telescope, which is inside that on a good night and beyond it on a poor one.

What the LER design puts first is eye relief at short focal lengths, which is where the standard approach usually gives ground.

When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that were not revealed at first glance. The broad field of view promotes the use of averted vision, which involves looking slightly to the side of a target object rather than directly at it. This is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.\u003c\/p\u003e\u003cp data-open-accessibility-text-original=\"16px\" style=\"box-sizing: inherit; -webkit-font-smoothing: antialiased; text-size-adjust: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); margin-top: 1rem; margin-bottom: 1rem; color: rgb(76, 81, 84); font-family: \" libre franklin sans-serif rgb font-size:=\"\" background-color:=\"\"\u003eAll Explore Scientific Waterproof Eyepieces are gas-purged and O-ring sealed to create a waterproof environment that is impervious to internal fogging and prevents contaminants like fungus and dust from entering the ocular housing.
