Sky-Watcher SWA-70 17mm 70° 2/1.25″ Eyepiece

The Sky-Watcher SWA-70 17mm eyepiece delivers a wide 70° field of view - perfect for sweeping views of open clusters, nebulae, and the Milky Way. The 2″ barrel lets in the maximum amount of light, and the included 1.25″ adapter means you can use it with a 1.25″ focuser as well.

Wide field of view for comfortable observing

A 2″ eyepiece gives you a noticeably larger field of view than a standard 1.25″ design. This matters most at low magnifications, when you want to frame large objects in their full extent. The 70° apparent field of view makes observing comfortable - you spend less time chasing moving objects or refocusing, and more time simply looking.

Compatible with most telescopes

The Sky-Watcher SWA-70 17mm works with any standard telescope that has a 2″ or 1.25″ focuser. It suits both beginners and more experienced observers who want a reliable, wide-field eyepiece for their kit.

What can you observe with this eyepiece?

The 17 mm focal length and wide field of view make this eyepiece well suited for:

Open star clusters - see the full spread of stars in a single view
Nebulae - take in large extended objects without losing the edges
The Milky Way - sweep along star fields with ease
The Moon - enjoy a broad, detailed view of the lunar surface

Who is this eyepiece for?

If you are new to astronomy, the SWA-70 17mm is one of the most practical first eyepieces you can own. A wide field of view makes it easier to find and centre objects - especially on a manual mount. If you already have experience, this eyepiece adds a capable overview option to your collection without a large investment.
