The SR 4mm eyepiece is a Symmetric Ramsden eyepiece that offers more magnification than a 2-lens Huygen eyepiece.
Some key features of the SR 4mm eyepiece include:
- Focal Length: The SR 4mm eyepiece has a 4mm focal length, which provides higher magnification compared to eyepieces with longer focal lengths
- Eye Relief: The distance between the surface of the eyepiece and where the image is brought to a focus is called the eye relief. This space is important for glasses wearers and for comfortable viewing
- Field of View: The SR 4mm eyepiece offers a 35-degree field of view, which determines the amount of sky visible through the eyepiece
