Takahashi UW Flat Field Series Eyepiece - 3.3mm, TAK-3.3UW (TEA0033)
Takahashi has just introduced the new TAK-UW ultra wide, flate field eyepieces. This original design series produces a flat field and a 90 degree apparent field view with pin point stars acros the field.
These eyepieces were designed to be used with the flat field FSQ's, Corrected Mewlons, Mewlons with MCR correctors. FS-60Q's and TOA's with flatteners and other flat field telescopes. These aplanatic eyepieces are free of coma and spherical aberration.
They are available in four focal lengths: 3.3, 5.7, 7 and 10mm to offer a wide range of magnifications with the same ultra wide flat 90 degree field.
This new design has 12mm of eye relief and an extendable eyecup for maximum shielding from stray light. All internal surfaces are painted with optical flat black paint to insure greatest possible contrast and to prevent ghost images.
Viewing with glasses is only necessary if there is astigmatism present in the observer's vision. Otherwise, the observer can observe without glasses and enjoy the ultra wide field of view.
