High-Power Eyepiece for Detailed Observing

The Tele Vue 4.7mm Ethos-SX delivers increased magnification with its 4.7mm focal length, bringing celestial objects closer for high-powered views. Its 110-degree apparent field of view provides expansive, immersive observing sessions. The eyepiece suits astronomers seeking detailed planetary or lunar observation with a wide perspective.

Consistent Optical Performance Across Sessions

The design combines contrast, colour rendition, distortion correction and centre-to-edge sharpness for a natural viewing experience. Compared to an 11mm Plössl with a 9.1mm field stop, this eyepiece provides greater power for higher resolution and a smaller exit pupil for a darker background. This enhances contrast to reveal deep-sky detail that exceeds expectations during sustained use.

Parfocal 1.25" Format with 2" Adapter Included

The eyepiece uses a 1.25" format and is parfocal with the 3.7mm model, simplifying swaps without refocusing. A supplied 2" adapter ensures versatile compatibility across different telescope focusers. Generous 15mm eye relief allows comfortable extended viewing and supports DIOPTRX lenses for astigmatism correction.

Questions about this item

How much heat or noise does the 4.7mm Ethos-SX produce during an all-night observing session?

The eyepiece is a passive optical device with no moving parts or electronics, so it generates no heat and makes no noise regardless of how long you observe.

What telescope focuser size do I already need to use the included 1.25" and 2" adapters?

Your telescope must accept either 1.25-inch or 2-inch eyepieces; the supplied adapters let the 4.7mm Ethos-SX fit both standard focuser sizes.

Will the 15mm eye relief on this 4.7mm eyepiece work with my older 11mm Plössl's diopter setting?

The 15mm eye relief is generous enough for most spectacle wearers and is independent of the diopter setting used on a different eyepiece such as an 11mm Plössl.
