TS-Optics 70° Wide Angle Eyepieces
The TSWA eyepieces are a very fine compromise between simple Plössl eyepieces and the extreme ultra-wide angle eyepieces. They already show a distinct wide angle effect, but use only 5 elements. The TSWA eyepieces are a further development of the classic ERFLE eyepieces. Also a big advantage of the TSWA eyepieces is the compact design. 1.25" eyepieces are only minimally larger than Plössl eyepieces and 2" TSWA eyepieces are also compact. This and the lightweight desing make the TWWA eyepiece the perfect choice even for telescopes with smaller focusers.

TSWA eyepieces are all-rounders for all fields of application
The versatile TSWA eyepieces provide a good performance in any application area. The eyepieces with shorter focal length are wonderful planetary eyepieces. They provide a sharpness like a good Plössl, but offer a wider field and a more comfortable view. The good contrast and the wide-angle effect make the TSWA also recommendable eyepieces for deep-sky observation. Multi-coating and blackened lens edges provide a pleasantly dark sky background. Fine nebula filaments become visible.

TSWA eyepieces do not need a built-in Barlow lens.
Many wide-angle eyepieces have a Barlow lens integrated at the bottom side. With this, a short focal length is created artifically. The TSWA eyepieces work without Barlow. Thios offers several benefits:
Less elements imply a brighter image and more contrast.
A very steady view, the 1.25" TSWA eyepieces are also very well suited for binoviewers.
The distortion is significantly reduced.
You can combine TSWA eyepieces with a Barlow lens, like Plössl or Ortho eyepieces. Tis is not recommended with eyepieces with built-in Barlow lens.
TSWA eyepieces have a very moderate focus position. You will be able to focus trouble-free with any telescope.

"Ich konnte keinen Unterschied zu einem günstigeren Plössl erkennen. Die Qualität an sich ist sehr gut. "

"Dieses Okular verwende ich an meinem TS Optics-Sucher 60/234mm. Die Optik lässt für diesen Preis nichts zu wünschen übrig.Durch das Gesichtsfeld von 70° habe ich am Himmel eine sehr schöne Übersicht von knapp 6° Feld. Zusammen eine sehr gute Kombination."

"Ergänzt mein erstes TS-Optics WA20 für das William Optics Bino und soll mir helfen mit seinen 70° zur besseren Übersicht bei offenen Sternhaufen. Sehr gut zu überblicken. Mechanisch recht gut verarbeitet, im Linsenbereich ein ungeschwärzter Metallring und sicher keine geschwärzten Linsenkanten. Zeigt beim Beobachten jedoch keine Reflechse. Somit empfehlenswert, auch Preislich. "

"Das TS WA-20 liegt sehr gut in der Hand und ist sauber verarbeitet. Die optische Qualität ist für den Preis in Ordnung. Ich benutze es unter anderem an meinem TS 60/234 zur Objektsuche. Es hat hier ein schönes WGf. von ca. 6°. "
