The large-aperture, fully multi-coated optics provide exceptional light
gathering capability for stargazing. For terrestrial observing, you will appreciate
Explorers’ long-distance range, wide field of view, and stunning resolution.
These are well made binoculars featuring BAK-4 prisms and internal baffling.
The barrels are cross-reinforced with an aluminum rod and objective cell
cuffs for maximum structural rigidity and unflinching optical alignment.
A sliding 1/4"-20 steel mounting post is held captive on the rod,
for coupling the binocular to a tripod (recommended) and achieving optimum
balance via the knurled knob, this (in my opinion) should have been made
from steel rather than from aluminium as the steel thread will strip the
thread off the knurled knob!
The eyepieces focus individually out to infinity (the individual settings
are shown on each eyepiece for convenience) which affords a higher degree of
focusing precision than center-focus mechanisms. The eyepieces have an 18mm
eye relief and each has an eye-guard that can be lowered to allow easy use
by people who wear glasses.
Viewing
I use the Orion for deep sky objects and comet hunting due to the substantial
light grasp and low magnification giving you good contrast. The Orion Giant-View
are a perfect way to help you familiarise yourself with star-fields and
the 2.5 degree field of view really makes it easy to hunt down those elusive
nebulae. M101 the spiral galaxy in Ursa Major at mag 9.6 to M97 The Owl
Nebula in Ursa Major at mag 12.0 will give you an idea of what can be observed
in the way of faint objects. M42 The Orion Nebula is just stunning, while
open star clusters are well resolved and will titivate a nights viewing!
On the brightest of stars there would seem to be a little scattered light.
The moon is just awesome during one of its phases showing you splendid
views of its craters and even ripples in its Mare.
