A camera system for mounting to a scope can include a camera portion and a mounting system rotationally coupled to the camera portion. The mounting system can include a first securing portion having a first securing member, where the first securing member is configured to abut against a first portion of an eyepiece of the scope. The mounting system can also include a second securing portion having a second securing member, where the second securing member is configured to abut against a second portion of the eyepiece of the scope. The mounting system can further include an adjustment mechanism that simultaneously moves the first securing portion and the second securing portion in opposing directions relative to each other.
