The Japanese made Baader Eudiascopic ED eyepiece is designed for maximum performance, not an inflated field of view.
Offers superior sharpness and colour correction when compared to an Erfle or Plossl, across the entire field of view.
So is the Eudiascopic essentially a Plossl on steroids?
Yes, but the 5-lens Eudiascopic is more than simply a 'Super Plossl'. It is a new eyepeice design in it's own right that outperforms a Plossl in every way. This is especially noticeable when it is used with a fast telescope like an f4-f5 Newtonian.
Tough, scratch-resistant broadband multi-coatings on all air-to-glass surfaces and edge-blackened optics provide maximum light transmission and contrast.
Generous eye-relief so is comfortable for use with eyeglasses.
The Eudiascopic ED 35mm delivers the largest possible true field from a 1.25" (31.7mm) nosepiece.
FOV is 44.4° for the 10mm and 45.6° for the 35mm.
Supplied with a large, removeable rubber eye shield.
