Oculair Explore Scientific 62° 32 mm — 62° schijnbaar gezichtsveld, 32 mm brandpuntsafstand

Explore Scientific 62° 32 mm eyepiece is a wide-field astronomical eyepiece with a 62° apparent field and a 32 mm focal length designed for visual observation through telescopes. It provides low magnification and an extended field of view that helps frame extended deep-sky objects and star fields while maintaining comfortable eye relief for prolonged observing sessions. The eyepiece is compatible with common telescope focusers in its respective barrel size and is intended for general-purpose use by amateur astronomers seeking wide, natural views.

Advantages

This eyepiece combines a relatively long focal length with a wide apparent field to deliver expansive sky coverage without extreme magnification. The 62° apparent field reduces the need for frequent re-centering when observing extended objects, and the optical design balances sharpness across the field with minimal distortion at common exit pupil sizes. The 32 mm focal length produces a comfortable low-power view ideal for locating objects and scanning star fields. Construction provides stable mechanical fit in standard focusers and straightforward handling at the eyepiece.

Suitable for

• Wide-field visual observation of star fields and large deep-sky objects
• Low-power scanning and initial target acquisition
• Observation with refractor, reflector, or catadioptric telescopes compatible with the eyepiece barrel size
• Use during public outreach or group observing where a broad view is advantageous

Key specifications

• Apparent field of view: 62°
• Focal length: 32 mm
• Optical purpose: visual astronomical observation
• Designed for standard telescope eyepiece barrel sizes (1.25" or 2" depending on the version)
• Low magnification suitable for wide-field viewing and target acquisition

How to use

Insert the eyepiece securely into the telescope focuser of the appropriate barrel size and tighten the focuser thumbscrews without over-clamping. Use the telescope’s focuser to achieve a sharp image of the target object; start with low-power pointing and then fine-tune focus. For best results with wide-field eyepieces, allow your eyes to adapt to darkness and position your eye at the eyepiece so the full field is visible without vignetting. When switching between eyepieces, re-center the target as needed and re-focus.

Recommendations

For comfortable wide-field observing, combine the 32 mm eyepiece with a telescope focal length that yields an exit pupil close to the human pupil diameter under your observing conditions; this maximizes brightness and field illumination. Use a secure mount and take care when changing eyepieces at night to avoid accidental contact with optical surfaces.
