The integrated field rotator allows the camera to be rotated to the desired orientation for best framing. The 2" and 1.25" accessories are clamped gently. In addition, the focuser offers an auxiliary thread for screw adaptations.

Included is a dovetail bar (Vixen style). Other dovetails can be connected, including Losmandy style ones. A carrying handle allows convenient transport and also mounting of accessories such as guiding scopes.

For photographic use, Tecnosky offers an optional 0.8x flattener/reducer that gives the apochromat a fast focal ratio of f/4.8.
