The SkyWatcher Photo-25 and 10 mm eyepiece pair for binocular viewer (2 pairs each) is an excellent starter kit for binocular observation.
Thanks to the design without eyecups, they can be easily mounted in popular mobile phone holders (not included), allowing us to capture the craters of the Moon with our telescope.
These models are characterized by a particularly favorable price and commendable performance. They are three-element, Kellner arrangement eyepieces, with one lens element made of barium glass for improved image quality. Despite their low price, they feature anti-reflective coatings. Their field of view is approximately 50 degrees, and they are primarily recommended for use in telescopes with a low focal ratio.
