I have a mint 9mm Planetary eyepiece for sale. This particular one was bought from Agena Astro last year. It's the same/very similar as the current TMB clones sold under various brand labels (Skywatcher, Olivon, etc)
The AFOV is 58º and eye relief is 16mm. The eye cup assembly screws up and down to adjust to your preference (like the Pentax XW models) but it also has a fold down rubber eye cup at the top. So it's easy to adjust for any observer and also keeps out stray light.
While this is not a premium eyepiece, it's a significant step up from the cheap Plossls supplied with most new scopes, both in terms of image quality and field of view.
