1.25" wide angle ERFLE with 20mm focal length and 70° field of viewTS WA eyepieces have good optical performance for a reasonable price.
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
The TS WA 20mm convinces with a particularly pleasant and quiet view. It is a very nice overview eyepiece for all telescopes and offers a high sharpness performance with all telescopes, even with very bright Newton telescopes.
The large field of view of 70° can be easily surveyed, even if you have glasses on. The generous eye relief and the quiet view make the eyepiece interesting for binocular applications as well. The field stop of the TS WA 20 is optimized for the typical Bino attachments.
The TS WA 20mm is suitable for any device with good sharpness performance over the entire field. Due to the high-quality multi-coating and the blackened lenses, the image brightness and contrast are also right.
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.
