Description
The Vigil 15x70 is a large-aperture binocular with 70 mm objectives and 15x magnification. The combination gives an exit pupil of about 4.7 mm, a true field of 4.0 degrees, and an apparent field of 60 degrees. At this power, star clusters separate into individual stars, and the brighter nebulae show more structure than smaller binoculars display under the same sky.
Targets such as the Pleiades, the Double Cluster in Perseus, and the Orion Nebula fill a good part of the field. The Andromeda Galaxy spans several degrees, so you can examine its bright core and the nearby outer regions from a dark site. Because the field is narrower than that of a 7x50 model, you will need to scan more slowly when you search for faint targets. Star charts marked with a 4-degree field help with that search.
At 2.1 kg, the Vigil 15x70 is too heavy to hold steady for long periods by hand. Mount it on a tripod through the central socket, using a tripod rated for at least 3 kg, and adjust the head so the binocular balances around its pivot point. A reclining chair with a stable mount lets you observe for extended periods without strain on your neck and arms.
An eye relief of 18 mm allows observation with glasses if you fold the eyecups down, although some eyeglass wearers lose part of the field. The O-ring seals and nitrogen purge reduce internal fogging during cool nights. Focus with the central wheel, and set the right-eye diopter on a bright star at the start of each session. Most adult observers with a dark-adapted pupil of about 5 mm or more use the full exit pupil under dark skies.
About this configuration
This listing covers one configuration of the Lanthorn Vigil 15x70 binoculars, defined by its package, optical coatings, armor color, and edition year. The parallelogram mount keeps the binoculars at eye level while you move them across the sky in smooth arcs. A parallelogram mount lets observers of different heights share the same view without aiming the binoculars again. ED glass reduces the color fringing that otherwise appears around bright objects such as the Moon and Venus.
The slate gray finish makes the binoculars easier to find on a dark table than the black armor does. The 2023 edition uses the same prisms and objectives as later years, with small differences in the eyecups. Compare the exit pupil in the specifications with your sky conditions and your age, since both affect how bright the view looks.
