Product Description
Diffraction limited "on-axis" performance is a given. Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, Tele Vue Plossls deliver sharper images than any other brand of 4 or 5 element "Plossl" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plossls feature full multicoatings for greatest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail. The sharper field focuses faint star light into perceptible points and allows those with undriven mounts to gaze longer before repositioning the image.

Very Good 25mm Plössl by TeleVue
By C. McColm
This is a wonderful eyepiece by TeleVue and a mainstay when I'm out viewing!Pros: The eyepiece is very clear, offers very high contrast, no apparent distortion or aberrations, and is a great low-power eyepiece (depending on the focal length of your scope in millimeters divided by your eyepiece focal length in millimeters--typically 300x power is considered max for atmospheric conditions, but be sure to check with your telescope's manufacturer). Although the field is about 50° with this eyepiece, the fact that it has less internal elements than wide-field eyepieces means that objects will be brighter (typically) with a Plössl like this. I own and use 11mm, 15mm, 20mm, 25mm, and 32mm Plössls by TeleVue and they outperform any Plössl out there. It is definitely worth a bit more to go with a higher-end eyepiece, especially since it is a purchase you'll only make once-- eyepieces don't really wear out if handled properly. :-) I've used this eyepiece for wonderful views of the moon and constellations. It is also very good for locating planets and seeing them in a wider visual context. However, you can boost it's power with a Barlow, which is what I sometimes do with a TeleVue 3x Barlow, only adding to it's versatility and with no real noticeable loss of brightness. I use this eyepiece often on a Orion XT8 every time I go out viewing and it is simply excellent.Cons: The eye relief on this 25mm is generous. I don't wear glasses, but this eyepiece should be useable for those who do. If you do wear glasses, however, generally Plössls like this may not be right for you and you should probably go with a TeleVue Radian (or similar longer-length eyepieces). The Radians are excellent eyepieces in their own right, but typically run about $180-$250. Other than that, it's hard to think of something that detracts from this eyepiece. It is not a wide-field eyepiece, but then again Plössls aren't wide field--it's just the nature of their design.Overall: A very, very good low-to-mid-power eyepiece that everyone needs for viewing and one that will blow away most any Plössl that came with your telescope and probably most Plössls in the aftermarket. To give you a sense of their value and quality, TeleVue includes a Plössl with their $3000+ refractors that they sell. :-)Thanks!
