متن يادداشت
"Anyone who has used a binocular telescope or even wide-field binoculars to look at the night sky will know just how breathtakingly beautiful the view can be when you observe with both eyes. Observing galaxies and nebulae with "regular" prismatic binoculars is just the beginning. Binocular eyepieces and adapters can be added to almost any commercially-made astronomical telescope. Specialized astronomical binoculars can also be home constructed or purchased complete. These range from modest instruments to giants that are basically two large telescopes mounted together." --Back cover
