Takahashi LE eyepieces could be considered as an improvement of the orthoscopic eyepiece design. The field of view of 52° is much better than the one of the orthoscopic eyepiece and the eye relief is much friendlyer. The eye relief of 13 mm is OK for the most eyeglas wearers. The normal observer won´t have problems with this eyepiece. This eyepiece very often will be used for planetary, moon and sun observations. Because of his slim design the eyepiece can be used in the binoviewer.
The Takahashi LE long eye relief eyepieces are a high quality line of eyepieces featuring Takahashi's proprietary LE deisgn and a 52 degree apparent field of view. Available in focal lengths from 2.8mm through 50mm, these eyepieces provide superior color correction and saturation and exceptional sharpness. The long eye relief makes the LE's easier for people who wear glasses.
Available focal lengths in a 1.25 inch design include 2.8 mm, 3.6 mm, 5 mm and 7.5 mm in ED extra-low dispersion glass, and 10 mm, 12.5 mm, 18 mm, 24 mm and 30 mm. A 2 inch, 50 mm flat field eyepiece is also available. All eyepeices feature multi-coated glass for maximum light transmission.
Here I have compared these 18mm eyepieces: Takahashi LE, Baader Classic Ortho, Starguider ED, Altair Lightwave Flatfield.
