For a good planetary / double star eyepiece, it is hard to go past either BGO ( Baader Geniune Orthoscopic) or Fujiyama orthoscopics. Compact design, simple lens configuration, only 40 / 45 deg. AFOV but that helps to concentrate on the subject, with a dark contrasting view.
The TMB "clones" are quite good performers as well, with a larger FOV which may help find and frame the target at high magnifications, at quite a reasonable price considering.

I had a couple of questions
1. There seems to be a lot of clones/knock off tmb’s on AliE and eBay, prices range from $30 to $70, is there any way of knowing or supplier that you’re getting the right one? Was after a pair of 9mm for binoviewing. In a small frac.
2. What would be your ultimate planetary/ double star ep?
Cheers
