Threads onto the back of the NexStar 4SE & GT.  This design allows you to look into the telescope at a 45° angle, at images that are oriented properly, meaning the image is upright and correct from left to right.

This high quality 90-degree multi-coated mirror diagonal allows you to take advantage of the wider field of view provided by 2" eyepieces.

Our Star Diagonal lets you view objects that are at a 90° angle from the direction the telescope is pointing, thereby allowing comfortable viewing when the telescope is pointed at, or near, the zenith (i.e. directly overhead). The resulting image is right side up, but will be reversed from left to right.
