These listings include a specialized 50mm aperture astrograph that prioritizes a wide field of view. It features SD glass within a quadruplet APO optical design to ensure high color correction and sharp details. The fast F3.8 focal ratio allows for shorter exposure times when capturing faint deep sky objects like large emission nebulae.

The unit comes with a 160mm Vixen dovetail plate, keeping the overall footprint very small and manageable. This makes it an excellent option for users with smaller tracking mounts or those who need a highly portable professional imaging rig. The mechanical build is robust, ensuring the internal glass elements stay aligned during transport.

This specific model is tailored for the needs of dedicated astrophotographers who value speed and field flatness. While the aperture is modest, the optical speed and glass quality provide impressive results for wide-field compositions. It is a compact solution for those looking to expand their imaging capabilities without carrying heavy equipment.
