Thanks to its 4-lens design, it offers a remarkably sharp and high-contrast image - ideal for wide-angle observation of the moon, star fields and nebulae. With a 50\u00b0 field of view, you'll see many objects fully in focus without constant adjustment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compared to inexpensive standard eyepieces, this Pl\u00f6ssl series delivers significant quality gains.
