Celestron Granite ED 7x33 Details

A mid-sized, low light performer, these Celestron Granite ED binoculars are a fantastic choice as an easy to carry and/or easy to travel with binocular perfect for uses like camping, hiking, birding and wildlife observation. This is especially true when light conditions are not ideal and/or at closer ranges. Thus they will suite environments like thick forests and jungles or for when the sun has just risen or is about to set.
The well-sized exit pupil along with high quality optics make certain that what light is available, gets transferred to your eyes for a brighter, better quality view.
A real highlight of this model is the extremely wide angle of view that they offer you. This once again is very important a closer ranges and especially when observing objects like small, fast and erratic moving birds and animals as it makes it much easier to firstly locate them in the view and then follow them.
With a minimum close focus distance of around 2 meters, these are also a great choice for the detailed observation of butterflies, other insects, flowers or even birds at a very close range.
By twisting down the eyecups, the 15mm of eye-relief should be just about enough to allow most eyeglass wearers to use these binoculars without the need to remove their glasses.

Description of Celestron Granite ED Binoculars

The pinnacle of Celestron binoculars is definitely Granite ED series. These binoculars received The Cornell Lab of Ornithology award and award for the best Binoculars of 2013 by Best Binoculars Review. They are suitable for bird watching, hunting, traveling, wildlife, nature and astronomy viewing and offer ultra-high performance, perfect even for professionals. Incredible performance is a result of an ED glass, fully multi-coatings of lenses, phase correction, with other features such as open-bridge design for comfortable handling and 100% waterproof and fog-proof construction for incredible protection and clear viewing. Granite ED also comes with a harness strap, helping you with comfortable portability.

Basic Features

Amazing Celestron Granite ED offers great ergonomic and aesthetic design. They are made out of ultra-light magnesium alloy that helps to decrease the weight and makes them incredibly light and fatigue free even when carrying them for longer periods of time. Beautiful aesthetic design and shape wrapped in black rubber armouring which is incredibly thick and able to protect them against impacts, makes them a real pleasure to use. The surface is rugged enough to prevent sudden slip out of your hands with the help of an open-bridge. This very welcomed feature allows you to safely and firmly grip the binoculars around the barrels and helps you to carry them with one hand when walking. Granite ED is also well protected with tight seals making them impervious to moisture, dust and other solid particles. You will never have to worry about exposing them to extreme weather conditions. With the help of nitrogen gas that is purged inside the construction, the clear view will never be compromised when facing sudden temperature changes, that makes the occurrence of condensation on the inner sides of the lenses.

Optical Properties

The Granite ED glass crafted in Japan, offers Extra-low dispersion ability for sharp images free of major distortion such as chromatic aberration and reflections. With the help of fully multi-coatings, these feature enhance light transmission rate, making images incredibly bright and also rich in contrast with accurate color reproduction. Superior image quality is also a result of phase coated prisms and high-grade BaK-4 prisms which offer razor sharp images even in the dim light. For focusing adjustments, the Granite ED offers smooth and quick central focusing knob, again, beautifully designed and rubberized for non-slip rotations with the help of the right-eye diopter. Granite ED eyepieces are rubberized and multi-positioned for ideal eye-relief for eyeglass wearers.


Granite ED binoculars comes with a carrying case for storage and neck strap for easier carrying. They are also equipped with objective lens and eyecup lens covers for additional protection.
