ATX (Angled) With its angled view, the ATX eyepiece module helps you to comfortably seek out your target. It also makes long-range observation significantly easier, especially when your subject is located in the sky, in a tree, or on a hill.

STX (Straight) Many people prefer the straight view of the STX eyepiece module because it allows them to observe and find moving targets, such as animals, more easily. It is also well suited to digiscoping and use in a car or stand.
