The TS SWM series eyepieces are multi purpose wide angle eyepieces, suitable for almost all astronomical telescopes
TS SWM 20 mm TS SWM eyepieces are powerful all purpose eyepieces for amateur astronomers.
They are suitable for many applications:
Lunar and Planetary Observing:
Through many details in the design the contrast has been maximized for excellent visibility of fine detail on the moon and on the planets. Ghost images and internal reflections are effectively suppressed. The long eye relief allows for long-term observing without tiring your eyes.
Deep Sky Observing:
A high grade multicoating minimizes reflection losses of light and offers excellent transmission. This is particularly important on faint objects that might be completely invisible in eyepieces with more lenses due to the resulting darker image. The large field of view is also very convenient for observing extended objects at high magnification.
The SWM is also well suited for projection astro imaging, both for classical eyepiece projection with SLR cameras and also for projection for compact digital cameras with integrated objective lens. For this application the large exit lens of the SWM eyepiece is an important feature!
for best possible light transmission
Comfortable Eye Relief / Large Exit Lens
The SWM eyepieces are fully suitable for eyeglass wearers.
Prevents stray light from entering the eyepiece from the side, and provides a soft surface as protection for eyeglasses.
Suitable for almost all telescopes
TSSWM eyepieces can be used on telescopes as fast as f/4.5 with reasonable image sharpness. From f/5 onwards field sharpness will be very good and can be recommended without reservations.
