Explore Scientific 5.5mm 100 Degree Argon Purged Eyepiece

This eyepiece should be a good match to short focal length refractors and fast Newtonian optical systems.

This newest addition to the Explore Scientific 100 Degree series was introduced with Argon as opposed to Nitrogen purging. All Explore Scientific 82, 100, and 120 degree eyepieces are expected to make this transition in 2014. In practical terms there is little difference in performance between these two gasses under the conditions an eyepiece will be used in.
