    SharpStar 61EDPH Mk III ED Triplet Apochromatic Refractor Telescope with 1.0x FLATTENER and f/4.4 0.75x Reducer/Flattener

    The ultimate portable astro photo and nature photography instrument!

    The 61EDPH series has long been popular with astrophotography amateurs. In order to further improve user experience, Sharpstar has optimized the 61EDPH Ⅱ and launched a new version - the 61EDPH Ⅲ.

    The Sharpstar 61EDPH Ⅲ has more diverse functions and greater performance. It is a great choice that can't be missed by astrophotographers.

     

    SharpStar 61EDPH Mk II telescope features:

    • 61MM f/5.9 three-element full separation optical design
    • Includes TWO ED lenses
    • New 2.5" dual-speed rack and pinion focuser, 10:1 fine focus
    • 2" and 1.25" universal interfaces
    • Angle adjuster for 360 degree rotation
    • Universal dovetail bar
    • Multifunctional handle
    • Comes with a finderscope mounting bracket (shoe)

    The new 61EDPH Ⅲ comes with high quality optical standards just like the previous versions and adopts a triplet air-spaced APO design. Compared to the 61EDPHⅡ, it upgraded to two pieces of low dispersion ED glass for more excellent imaging performance. It not only can be applied to visual observation, but also can provide higher-quality astrophotography. The 61EDPH Ⅲ has a focal length of 360mm, a focal ratio of 5.9, and supports the 44mm full-frame imaging circle. It is a high-quality portable telescope.

    The 61EDPH Ⅲ upgraded the handle of the 61EDPHⅡ to a multifunctional handle, which will accommodate a universal vixen-style finder scope base. In addition, the 61EDPHⅢ is equipped with a 200mm long vixen-style dovetail plate, so it is easier to connect to equatorial mounts and accessories, and makes the OTA easier to balance on the mount. The appearance has smooth and natural lines, with the classic red and white color scheme. The tube uses high-quality CNC machining, high-grade surface painting, and polished oxidation, elaborate and durable.

     

    The new F5.9 61EDPH Ⅲ has comprehensive upgrades on the primary lens, exterior design, and accessories, it is a telescope with high performance and versatility to meet the shooting needs of different users and provide a better shooting experience.

    Dedicated 2.3" f/4.4 reducer/field flattener is included in this bundle.

     

    DEDICATED FULL-FRAME REDUCER (included with this product listing)

    The special full-frame reducer of 61EDPH Ⅲ: One end of the thread is M68 × 1, connected to the primary lens 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 reduced to F4.4 and the focal length reduced to 270mm, is the first choice for deep sky astrophotography.

    DEDICATED FULL-FRAME FLATTENER (included with this product listing)

    In addition, the 61EDPH Ⅲ is also equipped with a special full-frame flattener, providing users with more options.

    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 unscrewed to reveal a 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.
