Telescope Eyepieces Lens & Filters

Telescope eyepieces lens and filters give you the ability to tailor your observations to the conditions and celestial objects you wish to explore. Eyepieces determine your telescope’s magnification: to calculate it, divide the instrument’s focal length by the eyepiece’s focal length. Having multiple eyepieces allows you to vary magnification levels and optimize each observation.

Eyepiece filters attach directly to or in front of the eyepiece to modify the light you perceive, highlighting fine details. They are particularly useful for observing the Moon, planets, or nebulae, enhancing contrast and improving visibility of delicate structures. Some filters also reduce glare or block stray light, providing greater visual comfort during your sessions.

Our selection of telescope eyepieces and filters fits various models and configurations, giving astronomers the flexibility to explore the sky according to their projects. Choosing these optical accessories from Astronomy Plus allows you to expand your observing capabilities and make the most of every session, fully leveraging your telescope and your stargazing experience.
