  • Sharpstar 2" Triplet 0.95x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors with M48 Thread

    Sharpstar 2" Triplet 0.95x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors with M48 Thread

    Sharpstar 2" Triplet 0.95x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors with M48 Thread

    Sharpstar 2" 0.95× coma corrector can be applied to most marketable Newtonian reflective astrographs. It’s of high quality and easy to use. Sharpstar 2" 0.95× coma corrector is designed for APS-C imaging circles(28mm), suitable for Newtonian reflectors with focal ratio between f/3 and f/6, and aperture size from 150mm to 600mm. The reduction factor is 0.95×, thus it can reduce the original f/4, f/5 and f/6 respectively to f/3.8, f/4.75 and f/5.7, effectively shortening the exposure time. Besides, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.

  • Sharpstar 61EDPHIII f/4.4 Full-Frame Reducer

    Sharpstar 61EDPHIII f/4.4 Full-Frame Reducer

    Sharpstar 61EDPHIII f/4.4 Full-Frame Reducer

    The special full-frame reducer of 61EDPH Ⅲ: One end of the thread is M68 × 1, connected to the focuser; the other end of the thread is M48 × 0.75 and has a built-in 2" filter thread. The back focus is 55mm. If it needs to be extended, the adapter can be screwed down to reveal the M54 × 0.75 male thread, and the back focus becomes 75mm. The focuser adopts a quadruplet air-spaced structure, supporting full-frame imaging. With the reducer, the focal ratio of 61EDPHⅢ is reduced to F4.4 and the focal length is reduced to 270mm, making the telescope the first choice for deep sky astrophotography.

  • Sharpstar 61EDPHIII Full-Frame Flattener

    Sharpstar 61EDPHIII Full-Frame Flattener

    Sharpstar 61EDPHIII Full-Frame Flattener

    The flattener: One end of the thread is M68 × 1, connected to the focuser; the other end of the thread is M48 × 0.75 and has a built-in 2" filter thread. The back focus is 55mm. If it needs to be extended, the adapter can be screwed down to reveal the M54 × 0.75 male thread, and the back focus becomes 81.5mm. The flattener adopts a triplet air-spaced structure, the peripheral light reduction control is excellent, can effectively improve the curvature of the field, improve the corner image quality, and reduce aberrations, so that users can take clearer astronomical photos.

  • Sharpstar 3" Quadruplet 0.85x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors

    Sharpstar 3" Quadruplet 0.85x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors

    Sharpstar 3" Quadruplet 0.85x Reducer / Coma Corrector for f/3-f/6 Newtonian Reflectors 

    Sharpstar 30085NTRD coma corrector can shorten the original focal ratio of f/4 to f/3.4, greatly shortening the exposure time. Besides, the Sharpstar 30085NTRD coma corrector is considerately designed with many threads. At the front of the corrector, there is M82×1 male thread for the connection to our 3" focuser. At the back of the corrector, there is tapped with M76×1 male thread, M68×1 female thread and M54×0.75 female thread, which can be used to thread on our M54 to M48 camera adapter ring. The back-focus is standard 55mm, starting from the M54 thread(camera end) to focal plane.
