Product Details

  • The optimized SCA260 is designed with an aspherical mirror which requires more sophisticated research and development. The process of producing, manufacturing and testing is more complicated compared with that of an ordinary reflective mirror, and the Pyrex-like material used is more stable than those traditionally used. The telescope is wrapped with durable carbon fiber material, which is lightweight, durable, and beautiful.


    Both the primary and secondary mirrors of SCA260 wear enhanced aluminum coatings, which ensure they can achieve a high reflectivity of more than 95%. We further simplify the optical axis mechanical structure.

    A 3" large corrector, featuring a three-element lens structure, is laid in the optical path, enabling the whole optical system to better achieve full-frame imaging and control the vignette.

    The delicately pierced handle bar is completely made from CNC-manufactured aluminum, which can be used as a base for the attachment of other accessories, optimizing the supporting mechanical construction and decreasing its weight.

    Based on the original, Sharpstar upgraded the travel length of the 3.35" dedicated focuser to 50mm for greater practicability. Also, Sharpstar upgraded the load of the focuser to allow you to add the accessories as you like, ensuring no slippage and smooth operation when shooting with accessories.

    Sharpstar also added a 360° rotator at the rear back of the focusing device, now there's no reason to worry about the EAF data line getting entangled in the process. Three section M68X0.1 thread, M54 × 0.75 thread and M48. In the 0.75 thread adapter ring, a built-in 2-inch filter thread is added to meet different needs, facilitate connection to most imaging terminals on the market and perfect focusing.
