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.

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.

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 F4.5 and the focal length is reduced to 270mm, making the telescope the first choice for deep sky astrophotography.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003ctable align=\"center\" cellspacing=\"0\" width=\"84.20%\" style=\"box-sizing: border-box;
