UW FLAT FIELD SERIES EYEPIECES
Takahashi has just
introduced the new TAK-UW ultra wide, flat field eyepieces. This original
design series produces a flat field and a 90° apparent field view
with pin point stars across 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°
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.
