Celestron 93431 Luminos 10 mm eyepiece 📷
Description:
This 10 mm eyepiece from Celestron's Luminos line brings a wide 82° apparent field for deeper, more immersive views of the night sky, useful for planetary observation and wide-field deep sky work. It combines a retractable eyecup and multiple anti-reflective coatings to help deliver sharp, defined images while remaining comfortable during long observing sessions.
Key Points
The eyepiece features an 82° apparent field of view which helps frame larger celestial objects and star fields, making it easier to locate and follow targets. The retractable eyecup extends when needed for improved eye relief and folds down for storage or when used with glasses. A rubber grip around the barrel gives a secure hold in cold conditions or when wearing gloves. According to the manufacturer, the Luminos design aims to balance wide field performance with comfortable ergonomics for amateur astronomers.
Technical Specifications
Name
: Celestron 93431 10 mm Luminos Eyepiece- Focal length: 10 mm
- Apparent field of view: 82°
- Construction: anodised aluminium barrel with multiple coatings
- Filter thread: yes, threaded for standard filters
Advantages
The multiple anti-reflective coatings reduce stray light and internal reflections, improving contrast and clarity for planets and brighter deep sky objects. The threaded barrel allows easy attachment of filters to adjust contrast or to isolate planetary details. The compact aluminium construction keeps weight low while remaining robust enough for frequent use in the field.
Usage Recommendations
For eyepiece selection, this 10 mm unit is a good choice when you want a mix of moderate magnification and a wide apparent field, for example when switching between lunar detail and open clusters. Fit the eyepiece into a standard 1.25 inch focuser and extend the eyecup if you are not using spectacles to improve comfort and eye positioning. Consider pairing it with lower- and higher-power eyepieces to cover a useful range of magnifications for different targets, and use filters threaded to the barrel to enhance contrast on planets and the Moon.
