TS Expanse 3.5 mm ED wide angle eyepiece for telescopes - 70° FOV - 1.25" and 2" barrel size ... top-of-the-line eyepice for visual observation and photography also 1.25" and 2" barrel sizes: Our TS Expanse eyepieces come with an integrated 1.25" and 2" barrel (both including filter thread). So you don't need to handle unuseful adapters in darkness when changing focal lengths. The TS Expanse eyepieces are ideally suited for nearly all kinds of telescopes. Image resolution and observing comfort are exceptional and can compete with all other makes in this price range. Even with fast systems (e.g. f/5 Newtonians), the Expanse series offers high off-axis sharpness. With the long eye relief and big lens, these models are not only good for visual purposes but also for photography. Big eye lenses: The TS Expanse series offer big eye lenses and a long eye relief of 20 mm. So you are able to enjoy these eyepieces even when you wear glasses! Viewing position is very comfortable, even with high magnifications. ED element and fully multi coated: An integrated ED element is responsible for the high degree of color correction. Additionally, all glass-air-surfaces are multi coated for maximum light transmission and a minimum of reflections. 70° apparent field of view: Its wide, fully useable field of view gives stunning astronomical impressions. "Tunnel-view" is past! Screwed camera connection: Expanse with T2 adapter T2 Adaptation: TS Expanse eyepieces come with an integrated M43x0.75 thread. Just screw off the rubber eyeguard and attach the (optional) HypT2 adapter. Now you have a solid screwed connection to T2 rings for your SLR camera or adapter rings for compact models. No tilting or off-axis problems any more!
