The massive 11-pound, 18-inch long Gemini® 25x100 are the ultimate in affordable long-range
observing instruments. The 25x100 size by far represents the most
bang-for-the-buck in the top aperture class.
These are heavy-duty giant astronomy
binoculars. Everything about these instruments says
"quality." Their attractive rubber armoring and hefty all-metal
CNC-machined and cast aluminum construction is guaranteed to last for many
years to come. The optical quality measures up to that of the precision
mechanics, which makes these excellent instruments for binocular astronomy
and wildlife observation. Fully broadband multi-coatings on all
air-to-glass surfaces (including the BaK4 porro prisms) ensure bright,
high-contrast images while minimizing internal reflections.
The 25x100 WP-IF version utilizes smooth,
CNC-machined individual focusers that provide the precision focusing
essential for maxim performance on astronomical targets. The outside of
each ocular is threaded to accept standard 1.25-inch telescope moon or
nebula filters, a great asset for those wishing to boost the capabilities
of their binocular even further.
Eyeglass wearers will appreciate the generous eye relief of 17mm. Collimation
can be adjusted by experienced users, if necessary.
Optical 25x100 binocular must pass a rigorous 14-point
inspection that insures a high degree of both optical and mechanical
performance, including accurate collimation. Any necessary adjustments are
performed by a highly experienced technician on a U.S. Navy Mark
V Collimator. Each 25x100 astronomy binocular is covered by our
two-year warranty and 30-day return policy.
An added perk is that every Gemini
Waterproof astronomy binocular comes with a deluxe heavy-duty carrying case
with durable PVC armoring and aluminum trim. The cases are lined
with soft, "egg-crate"-style foam for maximum protection.
25x100 WP-IF binoculars are the ultimate long-range observing instruments
in their price class. Ideal for stargazing or daytime use. Their huge
100mm (four-inch) objective lenses and strong magnification give them a
performance boost that simply can¹t be matched by lesser instruments. At
night, these binoculars excel at deep
space observation - nebulae, galaxies, and globular or open
clusters will all reveal detail you never expected to see in a binocular.
If you can make it to dark skies, you'll be amazed by their performance.
The 25x magnification makes them decent for solar system observing as
well, whether it's glimpsing the rings of Saturn and watching Jupiter's
moons, or simply observing our own moon. Keep in mind that the size
of these 25x100 binoculars and the resulting 11-pound weight will require
a hefty mount, though the awe-inspiring performance will be worth it.
