Lacerta 30mm Symmetrical Plossl Eyepiece 2-inch
One of the lenses is thicker than usual and the distance between the lenses has been increased as well. It's similar to a Brandon, but still not exactly the same.
Non-the-less it's a good example of what can be achieved if the lenses and the distances between them designed well.
Field of view: 58 degrees.
Theses are well corrected at the edges of the field of view, so that can be used up to f/4.8; can be compared with with more expensive eyepieces made from 5-7 lenses.
Eye relief is also comfortable: 17mm
All inner surfaces of the housing and lens edges are matte blackened.
4 fully multi-coated lenses in 2 groups.
A result of few lenses being used in construction is bright image with high contrast.
