The back focus is 55mm after the attachment of a camera. The maximum back focus can be extended up to 99mm if users add extra spacers(not included). The reducer is designed with a three-element air-spaced lens structure, supporting full-frame imaging, effectively controlling unwanted vignette.
The practical focal ratio of the Sharpstar 61EDPH when used with this reducer is f/4.5, and the focal length can be shortened to 275mm. It’s preferred by many deep-sky astrophotographers.
