1.25" wide angle ERFLE with 17mm 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
Despite the TS WA 17mm has a short focal length, it 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. Because of this
fact, this eyepiece a an all-rounder with a comfortable eye relief of 15
The TS WA 17mm 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.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.
