More product information
For little more than the cost of a conventional 60mm scope, the large 80mm objective lens of this Celestron Ultima spotting scope gives you over 77% more light grasp than a 60mm scope – and 33% higher resolution, too. This extra light grasp and resolution can help you make positive species identifications in poor lighting conditions, such as in twilight or under heavily overcast skies, and with almost no penalty in size or weight compared to a 60mm scope. This economical Celestron 80mm Ultima straight viewing spotting scope makes a big aperture spotting scope affordable for just about everyone.

For the birder on a budget, the 80mm straight viewing Ultima gives you more optical performance than you ever thought your budget would be able to afford. Compared to other 80mm spotting scopes, it is quite a bargain.

Optical features of this scope . . .

  • 80mm objective lens gathers over 77% more light than a 60mm scope for superior low light performance.

  • The crown and flint glass optics are multicoated for good light transmission.

  • The standard equipment 20-60x multicoated zoom eyepiece is specified at a generous 18mm eye relief at 20x. While this is technically correct, the actual usable eye relief of this and all other spotting scopes typically measures a mm or two less due to the recessing of the eyepiece when the soft rolldown rubber eyecup is in the down position for eyeglass use. There will be some minor vignetting of the field for eyeglass wearers at 20x. The specifications to the right are for the zoom set at 20x. At 60x, the field is 53’ at 1000 yards.

  • The scope close focuses to 27’. Through the scope, looking at a bird at this distance at even 20x would effectively be the same as looking with your unaided eye from only 1’ 4” away.
Mechanical features of this scope . . .
  • The scope’s long focusing knob is located at the top right front of the prism housing to allow precise focusing with either hand, even while wearing gloves or mittens. It is semi-recessed to resist snagging on clothing or carrying case and is grooved for a sure grip. Focusing is quite brisk compared to most scopes, with less than five turns of the focus knob needed to move from one end of the focus range to the other.

  • The Ultima’s straight through viewing makes it easy to quickly locate distant birds by sighting along the barrel using the sighting tube built into the left side of the body. For observing couples of varying heights who must share a single scope, however, the 45° viewing angle version of this scope (#CU80) will generally be more convenient for extended observing, as there is little need to constantly raise and lower your tripod to a comfortable observing height for each observer with a 45° viewing angle scope. Also, if you are tall, you will not have to crouch over to see through the 45° Ultima 80, as you would through this straight-through scope, saving you from a possible literal pain in the neck. A 45° scope is also more comfortable for watching treetop activity or for extended observing from a low tripod in a blind or on a back porch.

  • The scope mounts on any photo tripod having a standard 1/4”-20 thread mounting bolt.

  • The prism housing is lightly rubber armored to help shock-proof the optics.

  • A water-shedding stay-on soft case is standard equipment. The case has zippered fold-back flaps so you can use the scope on a tripod while it is still in the case. The case has an adjustable length shoulder strap for carrying.

  • The eyepiece is shipped in a protective hard plastic screw-top case. A separate zippered soft case (with snap-ring for attaching to a D-ring on the scope case) can hold the eyepiece, if desired. However, the scope case is shaped to fully cover the scope when its angled zoom eyepiece is attached, so you may find the separate eyepiece case to be redundant.

  • A snap-in camera-type lens cover protects the objective lens.

  • For photography, removing the soft rubber eyecup from the eyepiece exposes standard photographic T-threads. You can attach a 35mm camera body to the scope simply by threading an optional inexpensive T-ring onto the eyepiece and connecting your camera body to the T-ring. No separate camera adapter is needed. The scope becomes a fast 480mm f/6 telephoto lens with a camera attached.

  • A limited lifetime warranty is standard.
Magnification:
Magnification is the ability of a telescope to make a small, distant object large enough to examine in detail. If you look at the Moon (250,000 miles away) with a 125 power (125x) telescope, it's essentially the same as looking at it with your bare eyes from 2000 miles away (250,000 ÷ 125 = 2000). The same telescope used terrestrially will make an object one mile away appear to be only 42 feet away (5280 feet ÷ 125 = 42).
The magnification of a telescope is determined by dividing the focal length of the telescope (usually in millimeters) by the focal length of the eyepiece used (again, usually in millimeters; but in all cases by the same unit of measurement used for the telescope focal length). For example, a 2000mm focal length telescope and a 10mm focal length eyepiece will give you a magnification of 200 power (2000 ÷ 10 = 200). The same 2000mm telescope with a 20mm eyepiece will give you 100x (2000 ÷ 20 = 100).

Field of view 1000 yards:
105' @ 20x
Near Focus:
27'
Eye Relief:
Eye relief is the distance from the last surface of the eye lens of an eyepiece to the plane behind the eyepiece where all the light rays of the exit pupil come to a focus and the circular image is formed, sometimes called the “Ramsden Disk.” This is where your eye should be positioned to see the full field of view of the eyepiece. If you must wear glasses because of astigmatism, you’ll usually need at least 15mm of eye relief or longer if you want to see the full field of view with your glasses on.

A note on our eye relief figures: Quite often, our eye relief figures will differ from those of the manufacturer. This is because we measure the “usable” eye relief, while the manufacturers specify their usually-longer (but technically correct) “designed” eye relief.

The eye lens of the eyepiece is normally recessed below the rubber eyeguard or rubber rim of the eyepiece to keep the lens from being scratched during use. An eyepiece might have a “designed” eye relief of 15mm (and the eye relief will truly measure 15mm from the eye lens to where the image forms). However, if the eye lens is recessed 3mm below the eye guard, the Ramsden Disk forms only 12mm above the eyepiece body (the 15mm “designed” eye relief, less the 3mm of eye relief made unusable by having the eye lens recessed into the body of the eyepiece). This “usable” eye relief of 12mm (measured from the rolled-down eyeguard – the closest point you can get your eye to the eye lens – to where the image forms) is the eye relief figure we would measure and list in this website.

Why is it important to list the “usable” eye relief? For those people who don’t wear eyeglasses while observing, a few mm difference between the eye relief they expect from the manufacturer’s literature and the shorter eye relief they actually get in real life doesn’t mean a lot. They can simply move a little closer to the eyepiece to see the full field, and never realize that the eye relief is a little shorter than they expected. However, some people must wear eyeglasses while observing, because of severe astigmatism. These observers can’t move closer to the eyepiece if the eye relief is shorter than expected because their glasses get in the way. For these people, the real life “usable” eye relief is more important than the technically correct but sometimes not fully usable “designed” eye relief. We measure and list the actual usable eye relief so that people in the real world can pick the eyepieces that will work best for them.

18mm @ 20x
Exit Pupil:
The circular image or beam of light formed by the eyepiece of a telescope. To take full advantage of a scope's light-gathering capacity, the diameter of an eyepiece exit pupil should be no larger than the 7mm diameter of your eye's dark-adapted pupil, so that all of the light collected by the telescope enters your eye. (The eyepiece exit pupil diameter is found by dividing the eyepiece focal length by the telescope focal ratio.) Your eye's ability to dilate declines with increasing age (to a dark-adapted pupil of about 5mm by age 50 or so). For those in this age group, eyepieces with exit pupils larger than their eyes can dilate to simply waste their telescope's light-gathering capacity, as some of the scope's light will fall on their iris instead of entering their eye.
4mm @ 20x
Twilight Factor:
A number used to compare the effectiveness of binoculars or spotting scopes used in low light. The twilight factor is found by multiplying the size of the objective lens (in mm) by the magnification and then finding the square root of that result. The larger the twilight factor, the more detail you can see in low light. A twilight factor of 17 or better if usually required for reasonable low light use.
40 @ 20x
Aperture:
This is the diameter of the light-gathering main mirror or objective lens of a telescope. In general, the larger the aperture, the better the resolution and the fainter the objects you can see.
80mm
Length:
16"
Armored:
A binocular or spotting scope whose body is clad in rubber or polyurethane armor is said to be armored. Armor can be applied for looks, a better grip, noise-proofing, etc. An armored body does not guarantee that a binocular or spotting scope is waterproof, although most waterproof optics are armored.
Partial
Waterproof:
Yes
Photographic Focal Length:
The effective focal length of a spotting scope/camera adapter combination when the scope is used as a telephoto lens. The photographic focal length divided by 50 will give you the magnification of the combination compared to your standard camera lens.
480mm
Photographic Focal Ratio:
The photographic “speed” of a spotting scope/camera adapter combination when used for photography. The smaller the “f/ratio,” the faster the exposure (to capture birds in motion), or the dimmer the light level in which you can successfully shoot.
