Product Specs

The specs on the Celestron Regal are one of the main reasons that this spotting scope stands out even among more expensive competitors. Its ability to produce crystal clear images at a distance, as well as its uniquely comfortable eye relief, makes it an enjoyable and rewarding scope to use. Following are a few of its most important features:

• Diameter of objective lens: 80mm
• Optical coatings: Fully multi-coated
• Dimensions: 16.6in. X 4.6in. X 3.9in.
• Weight: 4.5 lb.
• Eye relief: 20mm
• Magnification: 20x-60x
• Angular field of view: 2.1-1.0°
• Focal length: 480mm


The Celestron Regal receives rave reviews from owners because of the clarity of the images it provides. These views are so outstanding that, according these reviewers, they match the views from more expensive spotting scopes. For instance, owners report that the views are excellent even at distances of 300 yards or more, and even for users (such as target shooters) whose precision depends upon obtaining a good view of the object being targeted.

There are a number of reasons that the Regal performs so noticeably well. One of these reasons is the ED objective lens that minimizes chromatic aberration and provides an accurate and sharp image of the object being viewed. Short for “extra low dispersion,” the ED glass from which the lens is made is designed in such a way as to minimize or eliminate the dispersal of light as it passes through the lens. It is this dispersal which can compromise the clarity of an image coming through a scope, so less light dispersal means a clearer and more accurate view.

In addition, the lenses on the Celestron Regal are fully multi-coated. This term refers to the fact that all of the lenses have been coated with multiple layers of a material designed to reduce light distortion through the lens. The combination of an ED objective lens with fully multi-coated optics allows the Regal to produce excellent images of objects even hundreds of yards away.

In addition to these superb optical abilities, the Regal possesses other features that make it comfortable to use even during long viewing sessions. For instance, the scope possesses an eye relief of 20mm. Reviewers note that this eye relief is extremely comfortable, allowing them to easily engage in intense sessions of observation. Adjusting the eyepiece to achieve maximum comfort is also a relatively simple process, requiring only the turning of the eyepiece while looking through it. The result is a scope that both performs impressively and is comfortable and easy to use.

Other features that make this scope both versatile and easy to use are a tripod mount that allows the scope to attach to a tripod of your choice (the tripod must be purchased separately). This mount allows you to choose from multiple methods for attaching the scope in order to allow you to mount the scope in the manner that is most secure and comfortable for your own use.
Some scopes are heavy and awkward to handle, making them more difficult to take out on nature viewing adventures. The Regal, on the other hand, is carefully designed to weigh less than most of its competitors. Its body is constructed out of a magnesium alloy that allows it to be 14 percent lighter than other Celestron models. The entire scope weighs in at less than 5 pounds, making it simple to carry around wherever you wish to enjoy your observation session.

The Celestron Regal is an appealing scope for a number of reasons. Its low price, for instance, makes it within the budgetary reach of many people who want to enjoy a quality observing experience. In addition, its superb optical features allow users to enjoy sharp long distance views, while its durable construction and lightweight body make it a pleasure to carry around. The result is a truly enjoyable way to take in all the views that nature has to offer.
