More product information
The 14mm Meade 100° field Extra Wide Angle 2” eyepiece provides entrancing wide field/medium power images with any size or type of telescope you may own that is capable of using a 2” eyepiece.

With fast f/ratio reflectors, such as Dobsonians, this 14mm Meade gives both an immense field and a bright image (with an exit pupil over 3mm with the typical f/4.5 Dob) that is very effective on nebulas. Its very wide field also makes it convenient for moderate power lunar and planetary observing with Dobs, as you have much longer to observe before the planet drifts out of the field and the scope has to be repositioned. That said, it is worth noting that the new 14mm Meade Extra Wide gives impressive views of open clusters, nebulas, galaxy clusters, and globular clusters with any telescope.

The 100° apparent field of this new 14mm Meade Extra Wide Angle eyepiece is nearly 50% larger in area than an 82° field eyepiece of the same focal length. You can use the field of view calculator below to see just how much sky the 14mm Meade Extra Wide Angle can reveal with your telescope.

The 14mm Meade Extra Wide Angle has high contrast, comfortable eye relief, and full field sharpness – with well-controlled astigmatism, field curvature, and lateral color. This 14mm Meade fits 2" focusers only. It is parfocal with the other Meade Extra Wide Field 2” eyepieces.

There is a soft rolldown eyecup to shield your eye from ambient light (from a neighbor’s security light, for example) and improve the image contrast. At an eye relief of 12mm, the 14mm Meade Extra Wide Angle would normally somewhat vignette the field of view for eyeglass wearers. However, since the 100° field is so wide that you can’t see the full field without having to move your head from side to side to take it all in anyway, vignetting in the conventional sense is not a problem.

Field of view:
The field of view (FOV) is the amount of observable world one can see at any given moment.
100°
Eye Relief:
Eye relief is the distance from the last surface of the eye lens of an eyepiece to the plane behind the eyepiece where all the light rays of the exit pupil come to a focus and the circular image is formed, sometimes called the “Ramsden Disk.” This is where your eye should be positioned to see the full field of view of the eyepiece. If you must wear glasses because of astigmatism, you’ll usually need at least 15mm of eye relief or longer if you want to see the full field of view with your glasses on.

A note on our eye relief figures: Quite often, our eye relief figures will differ from those of the manufacturer. This is because we measure the “usable” eye relief, while the manufacturers specify their usually-longer (but technically correct) “designed” eye relief.

The eye lens of the eyepiece is normally recessed below the rubber eyeguard or rubber rim of the eyepiece to keep the lens from being scratched during use. An eyepiece might have a “designed” eye relief of 15mm (and the eye relief will truly measure 15mm from the eye lens to where the image forms). However, if the eye lens is recessed 3mm below the eye guard, the Ramsden Disk forms only 12mm above the eyepiece body (the 15mm “designed” eye relief, less the 3mm of eye relief made unusable by having the eye lens recessed into the body of the eyepiece). This “usable” eye relief of 12mm (measured from the rolled-down eyeguard – the closest point you can get your eye to the eye lens – to where the image forms) is the eye relief figure we would measure and list in this website.

Why is it important to list the “usable” eye relief? For those people who don’t wear eyeglasses while observing, a few mm difference between the eye relief they expect from the manufacturer’s literature and the shorter eye relief they actually get in real life doesn’t mean a lot. They can simply move a little closer to the eyepiece to see the full field, and never realize that the eye relief is a little shorter than they expected. However, some people must wear eyeglasses while observing, because of severe astigmatism. These observers can’t move closer to the eyepiece if the eye relief is shorter than expected because their glasses get in the way. For these people, the real life “usable” eye relief is more important than the technically correct but sometimes not fully usable “designed” eye relief. We measure and list the actual usable eye relief so that people in the real world can pick the eyepieces that will work best for them.

12mm
Focal Length:
This is the length of the effective optical path of a telescopeor eyepiece (the distance from the main mirror or lens where the lightis gathered to the point where the prime focus image is formed). Focallength is typically expressed in millimeters.

The longer the focallength, the higher the magnification and the narrower the field of viewwith any given eyepiece. The shorter the focal length, the lower themagnification and the wider the field of view with the same eyepiece.
