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.

Customer Reviews:Greetings. I purchased this fine scope to use in NRA High Power &
Service Rifle Competition. I went with the 100 mm objective because I
need to be able to CLEARLY see .30 cal. bullet holes at 300 yards
without necessarily going to the maximum magnification. Talk about
clear...when I tested the resolution on tree limbs at 300-350 yards
distant from my position, I not only saw razor-sharp tree bark outline
but razor-sharp leaves as well. In fact, the resolution is far better
than any other scope I've ever looked through in this price range. These
48 year old pair of eyes were able to CLEARLY see ants and various
other insects plying the branches 300 yards distant on max. power
setting (67X). That's correct folks; clearly defined ants, flys, etc., @
300 YARDS!...not semi-fuzzy little moving blurs. In fact, I was able to
CLEARLY see them and identify them down to the 50X power setting. Color
resolution is also excellent. Eye placement is critical when you go
much beyond 45X but especially so at/near max. power because you're
dealing with very short eye relief and an exit pupil of about 1.25 to
1.50mm's. Optical resolution is incredibly sharp to about 90% of the
field with only very, very slight decline at the outer edge of the
field. You'll be able to clearly spot and see, with near perfect color
resolution, the eyebrow feathers of a Cocaided Woodpecker @ 300 yards,
never mind clearly defined .30 cal. bullet holes. YOU ARE going to need a
very steady tripod/stand for this scope, preferably one that has a 90
degree strong tilt collar to use at ground level. Best damn spotter for
the price I've ever looked through...and I've looked through quite a few
of them folks. You're not going to beat this performance package for
the price!!!
Pros: Finest Optical Glass & Prism quality for the price
Cons: Does not have a rotating tripod collar
by john,
from NE, United StatesBought and sent back 6 previouse spotting scopes trying to achieve a
visiual of 308 cal. holes out to 500yds on splatter targets for under
450.00 dollors.This scope absolutly performs that task. Spent about
379.00 including tripod. Have used several times at range dose not
disappoint. Just came back today observing my hits at 400 yds 308 cal.
in pretty heavy rain at about 35 power fine focus. Stay around mid power
at this range and im sure you will be quite pleased.It is a very heavy
scope dont scrimp on a cheap tripod. I didnt but I should have went
bigger/stronger. YOU can find the scope very reasonable. Celestron
Ultima 100 Model 52252 22x-66x power.If I sound like a salesmen remember
I sent back 6 previouse scopes to find what I neeeded.Had I had between
1000.00 and 1500.00 dollors I would have tried the Bushnell Elite
30x-90x-100 but I dont. This scope rocks especialy for the price. well
made too.
