Takahashi's wide field eyepiece
Monday, 30 July 2018  | 

Not many Erfle eyepieces labelled as such anymore.

Thus Takahashi 28mm 60 degree is their widest AFOV model. It has a niche of its own.

Not as sharp as the 45 degree 32mm Abbe Orthoscopic, but to me better than a 30mm LE model.

Best usable eye relief of any Takahashi eyepiece, due to the eye lens being near the top of its mounting barrel. Slightly better than a Tele Vue Plossl for eye comfort , and equivalent to a Baader Eudiascopic 35mm in my experience.
