Theodore Mattas Reviews
17mm Nagler type 4
I use this eyepiece with my 10SN f/4 and I have to say that it feels as if you look from a spacecraft window!!
Amazing wide field views, high contrast, sharp image.
A must have for anyone who loves wide field views from a large aperture scope.
a Nagler gem
Hello from Greece
I bought this eyepiece because I needed a medium magnification eyepiece to use with my 12 f/4 Newtonian.
It gives me 109X which I mainly use when I observe galaxies.
This eyepiece is lightweight and gives wonderful, sharp and high contrast views.
It is a no mistake investment for any serious astronomer.
Highly recommended
