Takahashi has just re-introduced their line of Abbe Orthoscopic
eyepieces. They feature the classic three and one configuration. These
eyepieces perform particularly well with the Takahashi 2x Barlow lens
and will produce a nearly flat field.
The Takahashi Abbe
Series is essentially par focal from the 6mm to the 32mm and is suited
to be used in turret eyepiece holder which makes changing eyepieces easy
as turning the turret to the desired eyepiece. Each of the four
elements is fully multi-coated for maximum light transmission which
significantly affects the contrast positively.
The Takahashi Abbe eyepieces are true to the original
Abbe design. They are fully multi-coated for maximum light transmission
for increased contrast. The 44 degree apparent field of view and high
contrast are perfect for lunar and planetary observing. When used with
the Takahashi 2X barlow the image field is nearly flat.
The Takahashi Abbe eyepieces come in 4, 6, 9, 12.5, 18, 25 and 32 mm focal lengths.
