Description

1.25" wide angle ERFLE with 20mm focal length
TS WA 20mm, 70° field of view

TS WA eyepices have good optical performance for a reasonable price; this is made possible by direct purchase from the manufacturer.

Especially in comparison with similar eyepieces, the TS WA convince with their better off-axis quality and very good transmission by fully multi coating and blackened lens edges.

Field of application TS WA 20mm:

The TS WA 20mm does not need an internal barlow element. So (if necessary) it can be combined with a barlow lens without loss of quality. Transmission and off-axis-definition are better, too.

The viewing position is relatively steady - this is a further advantage of the not existing barlow element.
The TS WA 20's field stop has the maximum size of standard binocular heads - here, this eyepiece gives the maximum field of view.

The TS WA 20mm is suitable for every kind of telescope - even with fast Newtonians it delivers good field definition. The high-quality multi coating and the blackened lens edges lead to a bright picture with high contrast. This eyepiece is recommended for lunar and planetary observations and for Deep Sky also.

The TS WA performance:

The transmission of the TS WA eyepieces can be viewed best by holding them against a white surface. Any colour difference or darkening will be visible immediately. With the TS WA eyepieces, the background remains relatively bright and colour-neutral. This is not a matter of course.

Many wide angle eyepieces can only reach their field of view by distortion. The TS WA eyepieces have nearly no distortion.
