Product Highlights
  • Waterproof
  • Angled Viewing
  • 22-66x Wide Angle Zoom Eyepiece
  • 39-66° Apparent Field of View

Celestron manufactures the Ultima line of Prismatic Spotting Scopes in 65mm, 80mm & 100mm varietals to suit your needs. The larger two can also be had with ED (extra-low dispersion) glass elements, an expensive product which produces a marked improvement in the color fidelity, resolution and edge delineation of the scope's imagery. All the Ultima line are mated to an eyepiece and render views which are both rightside up and laterally correct to the world, making them good for both terrestrial and celestial observing. All Ultimas are waterproof, making them more robust than ever before. Celestron surely is delivering exceptional value.

The Ultimas now offer the choice between 45° angled viewing or straight viewing as you prefer. Most users will prefer angled scopes because they are both simple to use for birds perched high above the viewer as well as easily simultaneously shared amongst users of differing heights. But some will prefer the straight viewing models, for these are much easier to use when hunting down the object of interest in the first place. Straight viewing models are also usually a bit lighter, brighter and less expensive. The choice is yours.

The Ultima 100 is amongst a handful of spotting scopes with an enormous objective lens diameter of 4", and as such is a large and weighty scope at that. But from dawn to dusk, and everything in between, you'll constantly be reminded of that objective lens size as everything you'll see will be that much brighter in the viewfinder.

Certain Celestron products include their wonderful "No Fault" warranty coverage, which assures that your binoculars will be repaired or replaced at Celestron's option for as long as you own them-no questions asked! The only requirements on the user's end are to ship the binoculars(at the user's cost) to Celestron with a proof of purchase and a check or money order for $25 to cover the costs of inspection, shipping and handling. This warranty service is valid only for USA and Candadian citizens purchasing from an authorized Celestron dealer.

Built-In T-Mount Threading for SLR Shooting
The Celestron Ultima series feature a T-mount threading upon the eyepiece barrel, allowing your scope to act as an ultratelephoto lens upon your SLR camera (digital OR film) with just the addition of a camera-specific T-mount adapter.

    After searching high and low for a good spotting scope, I finally found one! This scope is amazing! I have used Leapold, Redfield, and Alpen, which all are fine scopes but, when shooting at 400 yds it is extremely difficult to see your bullet holes in the target. My new Celestron 100mm lets in so much light and is crystal clear, that seeing my shots is a piece of cake. The wide view you get with a 100mm lens is amazing.

    At 22x the image was great - bright, clear and crisp. At any of the higher power setting the image quality went downhill in a hurry. At 66x (after refocusing) the image was a mess - color fringing, soft focus in the center, blurry out at the edges. I sent it back today.

    Comments about Celestron Ultima 100 4"/100mm Spotting Scope:

    Happy with this purchase; I primarily use it for birding and astrology viewing. I have attached a Canon 70D and have gotten some great shots of the moon and Jupiter. I like the clarity of the lens...it does fuzz out at max zoom but rarely need to max it. It focuses very quickly but does require a sturdy tripod...no cheap wannabe for this baby. I can read the expiration tag on a vehicle license plate at 400+ yards. I suggest a sturdy tripod that can support at least 11 lbs. and with a smooth ball head. Loving this Celestron.

          This scope was purchased to watch whales, shipping etc. from our living room.Our home is near Byron Bay, N S W Australia, and is set back from the coastline about a mile on a hill and therefore we need a reasonably powerful scope to see things effectively. We are very happy with its performance (which we need at full zoom), especially with the 100mm lens.With this type of use it is absolutely necessary to have it mounted on a good tripod, which we have.Altogether, great performance for the money.

              Comments about Celestron Ultima 100 4"/100mm Spotting Scope:

              I use this as a terrestrial telescope with some casual astronomical observing thrown in. I've owned some large, expensive telescopes, so I was curious how a sub-$ scope would do. The answer is: more than adequately. Yeah, the image starts to get a little fuzzy at the highest magnification, but it's still pretty good. Atmospheric shimmer is a bigger problem. I could have spent twice the money for an ED objective, but that probably wouldn't have netted me a big improvement. I mount the scope on a high-end carbon fiber tripod that I usually use with my Nikon D800; a solid mount is essential. Overall, a good buy.

                I just bought a house with a view of the Pacific and Agate Beach in Oregon and wanted to be able to check out fishing boats (coming out/going into Newport Harbor) and other things such as birds and surfers. This scope works well for everything. While it is a little light built I think that would be an asset if I decided to carry it somewhere (it does come with a nice carrying case). I also have Zeiss binoculars that I use as well and I can say that the Zeiss optics are much better (they should be at the price differential) but as I said, for the price the Celestron is a good performance/value choice.

                Comments about Celestron Ultima 100 4"/100mm Spotting Scope:

                First off, the thing is a beast. If your looking at 65mm spotting scopes this 100mm is far bigger. If size and weight are no concern, only bright clear optics go with this one. when I first got the scope I set it up at mt house and within a minute was able to read the lisence plate expiration tags (not the larger main number) from 150-200 yards.
                At full zoom the eye relief is acceptable and still fairly clear. For the money I'm very very happy.

                  I recently moved to a National Scenic Area and really enjoy this scope. First spotting scope, but have had scopes on rifles. Glad I spent a little extra to get the 100 mm. FOV and light gathering are excellent. In short, there are no distractions from the scope when viewing.

                    Comments about Celestron Ultima 100 4"/100mm Spotting Scope:

                    Used primarily for casual astro-observing. I was quite please with both the build quality (very solid) and optical quality (absolutely no apparent CA when viewing bright objects such as the moon or Jupiter). Images are crisp and clear - and with the micro focuser - they are easily brought into sharp focus. I have also used the Celestron Ultima 100, which although it is a good scope for its price - the difference the F-ED glass makes on the Regal is very apparent and well worth the extra cost.

                    Having owned a number of other scopes up to 10" Schmidt Newtonian - it is a real pleasure to go observing with this relatively light weight scope.

                    Comments about Celestron Ultima 100 4"/100mm Spotting Scope:

                    I just moved to a high-rise home, and was looking for something that I can use to view far away places.
                    For this price, the build quality is superb. The 100mm lens is smaller than I expected. It was easy to setup using some common sense. All components were in their pouches!
                    It was for home use hence its size was not a problem for me. However, do invest in a sturdy tripod.

                    This is my first spotting scope and I found the view to be just nice at 22x, but extremely hard to use at 66x. I am a glasses wearer.

                    I did find some purple chroma at high contrast areas but they weren't show-stopping at all.

                    Overall I am rather pleased at this first spotting scope of mine.

                      The product does it's job I returned it tough cause it gave me headaches but only me, my wife and my friend who looked trough it were fine.
                      I would have kept it if it was not for the headaches. Most people are not that sensitive, and this scope is the best for the price, the optics are good, images are sharp and the scope is clear.

                      Comments about Celestron Ultima 100 4"/100mm Spotting Scope:

                      I use this scope to look from my new appartment out to the ocean for watching whales moving up the coast and also watching ships coming into our port.
                      Light and easy to carry around on the tripod for different vantage spots
                      I just wish it had sharper immages on full zoom
                      I am no expert when it comes to spotting scopes and just bought it for a bit of fun in our new appartment but it is unbeleiveable how many of my friends use it when they come over
