It retains almost the same values of aperture, focal length, and appearance as the previous model.

61EDPH II uses the same smooth and solid F4.5 full-frame focal reducer (NOT included with telescope) to match their lens. The 2.3" reducer’s drawtube has a female M63×1 thread for the focuser of objective lens, the other end supplied external male M48×0.75 thread adapter for your camera to ensure the 55mm back focus requirement is satisfied. If you need to extend it, the back focus can be up to 99 mm by unscrewing the back adapter and configuring the adapter ring. The reducer features a triplet air-spaced lens, which supports full-frame optics, and eliminates color-fringing for exceptional control, available in 275 mm focal length, for an immersive deep-sky object astrophotography experience.

The 61EDPH II APO Refractor Equipment also includes a 10 cm dovetail plate, it has a screw-hole in the center that allows the camera to be mounted to a tripod for photography. The back end is equipped with a medium 2.5" rack and pinion precision focuser to be used with a large dedicated reducer, which is available optionally.
