The 5 mm model is the ideal choice for close-up observation of the Moon, planets or binary stars in very good atmospheric conditions.
The X-Cel LX series eyepieces from the renowned Celestron brand are designed with quality, comfort and image sharpness in mind. The 5 mm model is the ideal choice for close-up viewing of the Moon, planets or when observing binary stars in very good atmospheric conditions.
Key Features:
Focal length: 5 mm - suitable for very high magnification.
Field of view: 60° wide - provides an immersive image without the "tunnel" effect.
Clamping diameter: 1.25″ - compatible with most common astronomical telescopes.
Large eye relief (16 mm) - comfortable viewing even with glasses.
Multiple anti-reflective layers (fully multi-coated) - ensure maximum light transmission and sharp, high-contrast images.
Foldable eyepiece - for comfortable fitting of the eye, adjustable for viewing with glasses.
Robust metal body with rubberized surface - durable and pleasant to the touch, with a good grip even with gloves.
Recommendations for use:
The 5 mm eyepiece is ideal for:
Refractors (e.g. 90/900, 102/660, 100/1000) - offers maximum possible magnification, especially suitable for planetary observations.
Newtonian telescopes (e.g. 130/650, 150/750, 200/1000) - excellent for observing Saturn's ring, detailed structures on Mars or the moons of Jupiter.
Catadioptric systems (e.g. Celestron C6, C8) - allow extreme magnification, also suitable for separating close binaries.
Note: 5mm focal length is more demanding for atmospheric quality. It works best in calm air (good "seeing") and accurately aligned optics.
Comparison with other focal lengths of the X-Cel LX series:
7mm - slightly lower magnification, suitable for more versatile use.
9 mm - a compromise between magnification and comfort, excellent for longer observation.
25 mm or more - suitable for wide-angle views of star clusters, nebulae or object searches.
