Explore Scientific 100 Degree Eyepieces
Explore Scientific was the second company to enter the extremely wide field eyepiece market with the introduction of their 100 degree series. While other choices soon followed, this is the only 100 degree apparent field eyepiece that anyone ever seriously compares to the TeleVue Ethos. These are high quality eyepieces that represent a good value, and are certainly worth serious consideration whenever you find yourself in the market for extremely wide field eyepieces.
Extreme wide field eyepieces such as the Explore 100 Degree Series are most at home in Dobsonian telescopes where the added field of view allows more time before an object drifts from the field. The other major benefit of these eyepieces is that they allow you to apply more magnification to the same object while still allowing it to fit within the same field of view. We find this particularly useful when observing groupings of Galaxies.
