Explore Scientific UWA 14mm 100° 2″ eyepiece
If you are looking for an eyepiece that will literally pull you into the depths of the universe, the Explore Scientific UWA 14mm eyepiece with a 100° apparent field of view is exactly what you need. The 100° series from Explore Scientific has long been one of the most popular choices among demanding visual observers - and for good reason. The combination of an extremely wide apparent field of view, precise optics and solid mechanical construction makes it an instrument you simply want to spend entire nights under the stars with.
Optics and image quality
At the heart of this eyepiece is a 9-element optical system with fully multi-coated surfaces. This delivers maximum light transmission, high contrast and minimal unwanted reflections even when observing bright objects such as planets or the Moon. The 100° apparent field of view is truly exceptional in this price category - looking through the eyepiece feels like gazing through an open window into the cosmos, rather than peering through a narrow porthole.
Versatile use across the sky
The 14mm focal length makes this eyepiece suitable for a wide range of applications. It excels when sweeping large nebulae and open star clusters, and performs equally well at medium magnification on planetary objects. Wide-angle UWA 14mm 100° performance will be most appreciated by visual deep sky observers who want to get the most out of their telescope without compromising on image quality.
Comfort and compatibility
An eye relief of 14.5mm is a very respectable figure for an eyepiece with such a wide field of view. Observers who wear glasses will appreciate the fold-down eyecup, which allows them to set the optimal eye-to-lens distance while retaining the full field of view. The standard 2″ barrel ensures compatibility with the vast majority of mid-size and larger telescopes on the market.
The eyepiece is equipped with a filter thread, so you can combine it with any 2″ astronomical filter without adapters - whether a UHC, OIII or light pollution filter for observing from the city.
Who is this eyepiece ideal for?
- Visual deep sky observers who demand the highest image quality
- Owners of mid-size and large Dobsonians
- Users of apochromatic refractors and catadioptric systems
- Anyone looking to upgrade their eyepiece collection with a versatile mid-focal-length piece
Note: The weight of 850g should be taken into account when balancing the telescope, especially with refractors or Newtonians on lighter mounts. This is a robust instrument that deserves a correspondingly solid setup.
