  • Upgraded from 1 to 2 elements of low dispersion ED glass for vastly improved imaging
  • Focal length is slightly longer at 360mm compared to 335mm if gen II
  • Upgrade handle with universal vixen-style
  • Comes with a 200mm long vixen dovetail
  • New reducers and flatteners are now available for gen III, giving photographers more flexibility in their focal lengths

This is a great choice for anyone looking to get a small imaging scope in the 270-360mm focal length. Always has been, now it's even more so!

Product Description

Please note that EDPHII has been discontinued. Generation III is the new official 61EDPH

The new 61EDPH Ⅲ still has high-quality optical standards like before 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. 61EDPH Ⅲ has a focal length of 360mm, a focal ratio of 5.9, and supports the 44mm full-frame image circle. It is a high-quality portable telescope.

The 61EDPH Ⅲ upgraded the handle of the 61EDPHⅡ to a multifunctional handle, which can be connected to the universal vixen-style finder base. In addition, the 61EDPHⅢ is equipped with a 200mm long vixen dovetail plate, easier to connect to the 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, very simple and generous. The tube uses high-quality CNC machining, high-grade surface painting, and polished oxidation, elaborate and durable.

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.

In addition, 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 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 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.

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.
