Explore Scientific Eyepiece 100° 9 mm 2″

The Explore Scientific Eyepiece 100° 9 mm 2″ offers an unparalleled viewing experience - it feels like you are floating among the stars instead of looking at it. With its huge 100° field of view, this eyepiece combines impressive magnification with a panoramic perspective, ideal for those who want to fully immerse themselves in the night sky.

The optical design with nine lenses in six groups delivers razor-sharp, high-contrast images across the entire field of view. Sharpness is maintained even at the edges, making this eyepiece special when observing open star clusters, globular clusters or large planetary nebulae.

The high-quality EMD multicoating ensures maximum light transmission and minimizes reflections. In addition, the eyepiece is gas filled with Argon and completely waterproof, so that dust, moisture or mold do not have a chance. This guarantees years of worry-free use, even in high temperature changes or humid nights.

The adjustable eye cup enables comfortable use, including for eyeglass wearers, while the generous eye relief of 12.5 mm Ensures a relaxed observation posture.

Application:
The Explore Scientific 9 mm 100° eyepiece is ideal for:

• high magnifications at moon and planet observations;
• contrasting observations of globular clusters and nebulae;
• Telescopes with medium to large apertures (from 150 mm).

Thanks to its 2″ connection, the eyepiece fits virtually all standard focusers and offers a spectacularly wide image, even on fast f/5 Newtons.
