Description
The Pennant 10x50 is a roof-prism binocular with 50 mm objectives and 10x magnification. The 5 mm exit pupil matches the dark-adapted pupil of many adult observers, so the view stays bright while the magnification separates close pairs and shows the larger star clusters clearly. The 6.0-degree true field gives an apparent field of 60 degrees, which keeps a wide sweep of the Milky Way in view. Exit pupil and field size together set the balance between brightness and sweep speed.
The 10x50 suits targets that reward steady magnification, including the Double Cluster in Perseus, the Beehive in Cancer, the Pleiades, and the globular cluster M13 in Hercules. At 880 g the binoculars show small hand movements at this power, so brace your elbows against your chest or rest them on a wall or car roof. Sweep slowly along the Milky Way from Cygnus toward Cassiopeia, and note which clusters resolve into individual stars.
The BaK-4 roof prisms are phase-corrected and fully multi-coated, which keeps star images sharp toward the edge of the field. The 15 mm eye relief lets you keep eyeglasses on, though observers with deep eye sockets may need to fold the eyecups down to see the full field. The central focus wheel moves smoothly, and the right-eye diopter compensates for differences between your two eyes.
The body is nitrogen-purged and sealed against moisture, so you can use it on damp nights and in cold air without internal fogging. The 3.5 m close focus lets you view nearby terrestrial subjects as well as the Moon, which shows crater detail along the terminator at 10x. Store the binoculars in the soft case with the caps fitted to keep the lenses free of dust.
About this configuration
All configurations of the Quillon Pennant 10x50 binoculars share the same magnification and objective size; the options below change the package and finish. The included tripod adapter lets you fix the binoculars to a photo tripod for steadier, more relaxed views. With the adapter on a tripod, hand shake disappears, which makes faint stars and close double stars easier to see. The ED version adds low-dispersion glass and full multi-coating for sharper star images toward the edge of the field.
The black armor is the standard finish of the Pennant line and matches its black lens caps. The 2026 edition carries the optics over unchanged and updates small parts such as the caps and the case. Before you add a mount or adapter later, check the compatibility notes for the thread and fitting that this binocular uses.
