Celestron Luminos 7 mm - 1.25"

In a typical 8" f/10 Schmidt-Cassegrain telescope (2032mm focal length), the Luminos 7mm eyepiece provides a high magnification of 290x. This is an excellent power for detailed views of Jupiter's Great Red Spot and major cloud belts, as well as the rings of Saturn, provided seeing conditions are stable. The 82° field will give you a wide, immersive view, making the planet feel like it's suspended in space.

The 12mm of eye relief is on the shorter side for observers who need to wear glasses to correct for astigmatism. While some users with minimal correction might see most of the field, those with thicker lenses will likely experience a restricted field of view. For non-eyeglass wearers, the pop-up eyeguard makes it easy to find a comfortable viewing position.

Being parfocal means that the Celestron Luminos 7mm will reach focus at the same point as other eyepieces in the Luminos series. This allows you to switch between, for example, a low-power 23mm Luminos and this high-power 7mm Luminos with minimal or no need to adjust the telescope's focuser, which is a significant convenience during an observing session.

An 82° apparent field of view creates a much more immersive experience than standard 50° eyepieces. At the high magnification provided by the 7mm focal length, this wide field makes it easier to track celestial objects as they drift across the sky and provides a "spacewalk" feeling that many observers prefer for planetary and lunar observation.

Yes. The 1.25" barrel of the Luminos 7mm is threaded to accept standard 1.25" astronomical filters. This allows you to easily attach neutral density filters for observing the Moon, or colored filters to enhance specific features on planets like Mars or Jupiter.

The eyeguard is adjusted by twisting the rubber grip that runs around the middle of the eyepiece body. A simple twist will raise or lower the eyecup, allowing you to set the optimal distance from the top lens to your eye for maximum comfort and to block stray light.
