This scope features a variety of standout components, including the XLT coating, ED objective lens design, rotating tripod mount, and the magnesium alloy body.

Lens Quality

The scope’s objective lens produces a vivid, clear image. It’s able to replicate images in a precise, high-quality color scheme, shows remarkable color contrast, and reduces chromatic aberration.

The eyepiece mount measures in at just over an inch and features a twenty-millimeter eye relief, a rubber eyecup for improved comfort, and a better than average magnification range of 16x.

The patented Celestron’s lens coating helps to produce bright images and rich, full colors. The extra low-dispersion glass and BAK4 prisms work together to reduce chromatic aberration.

The ED glass is often found in higher-end scopes and binoculars. The addition of ED glass allows for improved light transmission while helping to prevent light interference and other types of optical issues that are common in lower-priced scopes. And the result? A high definition viewing experience, high contrast, and rich color fidelity.

Dual Focus

This model features the collar style focus ring, which is located on the slimmest portion of the eyepiece. The design allows you to focus much faster than you’d be able to with a standard knob focus setup. This means, once you sight your target, you can swiftly zoom in.

Viewing Range

This scope offers a viewing range of sixteen feet to one thousand yards and features close-focus capacity for precision and clarity.

The lens is created out of the same type of materials that are used for telescopes. The scope’s extra-low dispersion glass will help users to sight even the smallest species of birds in the dimmest lighting conditions, even if they’re hiding in thick brush. The scope is able to provide maximum light transmission regardless of the environment or situation. Additionally, the scope’s dual focus knob is easily accessible so you can quickly make adjustments to the focus and instantly enjoy a crystal clear viewing experience.

Smartphone Adapter

Now, you can instantly share your birding experience with family and friends thanks to the included smartphone adapter, which is compatible with both Android and iPhone devices. The adapter will allow you to attach the phone’s camera to the scope’s twist up lens and take high-quality photos and email them to family and friends or share it to your social media accounts.

Stay-On Case

The stay-on case is another great free accessory and one that will provide your scope with some much-needed extra protection against damage and the elements.  Most models in this price range will not come with a custom carrying case, so this is a big selling point for buyers.

Tripod Design

The included tripod allows you to easily adjust the angle and height of the tripod in seconds. This rotating tripod makes it easy to set up your scope or change positions. Once you have it in the ideal position, the tripod will snap into place using a unique locking system. This will give birders peace of mind knowing that the tripod will remain firmly in place during use.


The scope’s lightweight design makes it a popular option for the backcountry birder who enjoys hiking to remote locations in order to sight rarer species. The scope’s design makes this model extremely portable and fourteen percent lighter than other models produced by this manufacturer. This is all due to the lightweight magnesium alloy body. While the material helps to cut down on the scope’s weight, it’s also incredibly durable.
