Explore Scientific 100 Degree Eyepieces

Explore Scientific

Explore Scientific was the second company to enter the extremely wide field eyepiece market with the introduction of their 100 degree series. This is the only 100 degree apparent field eyepiece that anyone ever seriously compares to the TeleVue Ethos, and they do represent a good value in the arena of extremely wide field eyepieces.

Nitrogen to Argon Purge Transition

Beginning in 2013, Explore Scientific started transitioning away from Nitrogen and towards Argon gas for purging the void space within their eyepieces. As of July 2014, only the 20mm 100 degree eyepiece is available as a Nitrogen purged eyepiece.
