These binoculars give you an amazing stargazing experience, with a good combination of magnification, aperture and portability.
Construction: Centre focus, nitrogen-filledAt night, stars that are too faint to be seen with the naked eye spring into visibility, while the larger nebulae, galaxies and star clusters become recognizable glows. Just scanning along the Milky Way on a good night is something that even experienced observers never tire of.
The colors of the stars are also much more obvious. We chose to look at a notably red star, fourth magnitude Mu Cephei. To my eyes, this just looks like another star with the naked eye, but through the 15 x 70s it burns like a glowing coal. You can see why William Herschel referred to it as the Garnet Star.
The sight of the full Moon through these binoculars is a show-stopper. Using both eyes rather than just one as with a telescope gives a dramatic feeling of depth, even though there is no actual stereo effect for any object more distant than a few hundred meters. Viewing a bright Moon provides a good opportunity to look for chromatic aberration introduced by the optics.
The binoculars have a generous eye relief of 17 mm, which means that you don’t need to get your eyes very close to the eyepieces in order to see the full field of view.
