Image-stabilized binoculars

<h2 id="active-systems">Active systems</h2>
<p>In these systems the change in attitude of the binoculars is sensed electronically, and some part of the system is changed to correct this offset. A lens group may be shifted, or the angle of a fluid filled <a href="/facts/Prism_(optics)/eodBFF70">prism</a> may be changed.
</p>
<h2 id="passive-systems">Passive systems</h2>
<p>In these systems there is no feedback from a sensor to the corrective element.  The whole binocular may be stabilized by use of a <a href="/facts/Gyroscope/UjXGsfMq">gyroscope</a>, or the binocular prisms may be disengaged from the housings, allowing them to be unaffected by binocular movement.
</p>
<h2 id="use">Use</h2>
<p>Image-stabilized binoculars are frequently used when viewing from a moving object such as a boat or plane. They are also very helpful with high powered binoculars.  Image stabilized binoculars have become popular with amateur <a href="/facts/Astronomer/ronF8j4a">astronomers</a>.
