William Optics 40mm 2″ SWAN Eyepiece

Step into a bigger picture
The William Optics 40mm 2″ SWAN eyepiece feels like opening a window to space. The wide 72° field of view gives you a relaxed, immersive viewing experience. You see more at a glance, without having to constantly search or move.

Clear, calm and comfortable viewing
The multiple coating keeps your image bright, so that stars and nebulae are shown off beautifully. The lens edges are finished in black, reducing stray light. This makes for calm images, especially with faint objects. With 28 mm eye relief, you'll look comfortable even when wearing glasses. Your eyes remain relaxed even during long observations.

Modern design with practical benefits
The eyepiece uses five carefully designed lens elements. That gives you sharp stars all the way to the edge, keeping your image wide without distortion. The folding eyecup helps you block light and find the perfect viewing position. Thanks to the 2″ connection, the eyepiece fits many telescopes. You easily screw on filters for even more detail, for example on the Moon or bright nebulae.

For anyone who wants to look big
Whether you want to make the Pleiades sparkle or explore wide nebulae, this eyepiece gives you peace, space and detail. It feels instantly premium, but remains surprisingly accessible.
