Eyepieces TS Planetary ED 18 mm

The new TS planetary ED eyepieces have a 5/6 element optics with the use of ED (Extra Low Dispersion) glasses, are particularly suitable for planetary and lunar observation in high resolution where the absence of aberrations results from a increased detail.
The 16mm pupil extraction and helix bonnettes make them very comfortable even for those wearing glasses. The apparent field is 60 ° and makes them interesting, in the longer focal lengths, also for observing deep-sky objects.
Elegant mechanical construction with 2 colored bands that distinguish each focal point.
