    • Excellent value. High quality at a very affordable price.
Style: Ultima 100 - 45°
I'm really pleased with this purchased equipment. Gross cost with S&H was $230. It has wowed expert and fanatical "Gonzo" Colorado birdwatchers who are using scopes costing $2000 to $3500. Nothing but compliments and highly favorable comments from folks with discerning optical tastes. I'm not an optical expert but; I can't find anything to complain about, so far. Perhaps a year from now after extensive field use I'll learn of small flaws and deficient effects. If I do I intend to update this review. It is rugged enough for frequent field use on trails and wet weather. Does not fog up. It's a bit heavy at 4.5 lbs. due to the 100 mm objective lens. However, that lens is still bright and sharp at full 67x magnification even in twilight or predawn light. Resolution and sharpness even at very long range are excellent. Quick & easy to focus or change magnification. [One person told, "I think I paid $3000 more to get 10% to 15% better image quality. And I have to baby mine!"] Seems solidly built and overall fit, finish and workmanship seem more than satisfactory. If you're on a tight budget, think seriously about Celestron products. ... show more

    • Awesome Spotting Scope
Style: Ultima 100 - 45°
I purchased this spotting scope to replace one that had only a 60mm objective lens and was a 20x60 zoom magnification.My old spotting scope did not perform well at all at higher magnifications.Images became increasingly difficult to see as you increased the magnification because of the amount of light that was lost. At anything around 100 meters a 22 caliber bullet hole on a white background was difficult to distinguish and on a black background could not be seen at all.The Celestron with the 4 inch(100mm)objective lens eliminates all of the light loss problems.This is a really awesome piece of glass for target shooting.I can now see 22 bullet holes at 300 meters. One word of caution.Do not buy a cheap tripod to use with this spotting scope.Any light weight or medium duty tripod will not hold this beast steady.I would think that a video tripod would be the way to go for bird watching and nature studies.I made the support for mine since I only use it for target shooting.I used a 6 inch steel c-clamp and a 3/4 inch solid brass rod all bolted together with a sturdy ball head mounted on the brass rod.This whole contraption is then mounted to a concrete shooting bench.I tried initially to use a medium duty carbon fiber tripod(100 dollar range)but it was just not up to my needs for stability(close but no cigar)All in all this is the best spotting scope I have seen at the range where I shoot.It is large, and very nice to view thru when mounted on a steady and stable support.I would highly recommend this spotting scope to anyone that needs plenty of light coming down the tube. ... show more

    • 4.49 stars. the best value spotting scope out there bar none.
Style: Ultima 100 - 45°
the only reason i'm dinging this scope at all is that the large lens cap that came with it doesn't fit the scope right or its ridge is damaged such that it barely fits on it and falls off if you sneeze or look at it wrong. so total F for the lens cap....but the scope!!! the scope itself is so worth well beyond the money. i stared through leupolds and vortexes that were many many times the price of this scope while shopping around, but based on the reviews here at amazon decided wth, i'll give this celestron a try. i had purchased a celestron microscope for my kids in the past and was impressed with its quality so i thought why not. well, i'm so glad i didn't shell out 4 digits for a more expensive scope because this scope delivers. the quality of glass amazed me. it was very very clear. at 150 yards and less i could CLEARLY see .223 holes made on WHITE paper. when you get further, you can still see it but like all scopes once you have to zoom out too far, the shake makes it harder to see. i took this scope to the range with my friends--one of whom had the 4 digit vortex scope which was definitely quality, but provided no better of a view than my celestron. seriously, no better of a view. they looked equally clear and had the same zoom. we spotted each other for hitting big steel targets at 300 and 400+ yards! back at home, the spotting scope also works beautifully to look at stars or bird watch with the kids. you absolutely need to get a quality tripod for a any spotting scope and this one is no exception. in fact, make sure your tripod is sturdy. as you can see, this scope is very front heavy and you don't want to tip over. also, there are camera adapters available for this scope so you can take pictures of your spotting scope view. i haven't tried this yet but mean to in the future. this scope is one of my "phew!" purchases of the year. the kind where you take a chance and are just beyond satisfied. very very happy with it! it is perfect for the shooting range. ... show more

    • Quality and Effective
Style: Ultima 100 - 45°
I'm not terribly excited that this product came from China. While I appreciate the Chinese, their economy, and our trade relationship, I find too often that that relationship comes at the expense of product quality, environmental degradation, and local jobs. However, I will admit that this product is quality and comes at a competitive price! I do hope that working conditions for those at Celestron are safe and healthy. Should I find out otherwise, they will join the list of companies that I will not support with my financial vote. For now though, thank you. I am enjoying this spotting scope immensely. I use it for daytime distance viewing and star gazing. I was able to find a t-ring and adapter locally that allows me to film HD video at over 67X (the scope's inherent magnification + the camera's zoom). It's become something my wife and I both enjoy. I also find it terribly effective at helping our local gas industry stay honest. Filming in incredible detail removes any doubt as to "what they're up to." ... show more

When I originally ordered this Ultima 100 spotting scope, I was expecting a decent low-end scope for recreational use on my condo balcony, which overlooks Manila Bay. What I didn't expect was the extremely high-quality image it produced over its entire range and its high-quality construction. Of course, this is no Kowa or Zeiss, but it turned out to be a 'serious' scope that more than adequately resolves the portholes on ships far off on the horizon, that can barely be seen with the naked eye. I'm a fan. One thing I did do, which makes an important contribution to image quality, is mount the scope on a very heavy-duty tripod (an old Leitz Tiltall designed for 4X5 cameras). I mounted the scope with the Celestron tripod extender, which is bundled in the box, but I set it up with a different arrangement than Celestron recommends (see photos). I screwed the scope to the extender's tripod screw in such a way that the forward barrel rests on the far end of the extender. This arrangement provides two points of contact instead of just one, eliminating 'tuning fork' vibrations which would occur if the forward barrel were just hanging in the air. Before tightening the mounting screw, I inserted a small felt pad between the surface of the extender and the scope's barrel to protect the barrel from scratches, ... show more

    • Works at low power.
Style: Ultima 100 - 45°
I was really excited about the 100mm front objective - but in this case you get what you pay for. The eye-box is bad. The clarity at max magnification is nearly unusable as it appears you are looking down a straw. I found that much beyond 40x was nearly impossible to use. On a good note, I liked how well the focusing knob worked. And the tripod mount is robust. Yes - it will work in a pinch, but the cost cutting shows. ... show more

    • High quality scope for the price, albeit its heavy weight and requirement for a heavy duty tripod.
Style: Ultima 100 - 45°
I use spotting scopes for several purposes: Star Gazing, Looking around the valley, target shooting, enjoying the moon, and bird watching from home. We live on a mountain view home with a moderate sized piece of land. A nylon carrying bag is a provided but it is not protective in the sense of drops or shock. The covers for the objective and eyepiece are rudimentary. This scope doesn't come with a tripod. It needs a heavyweight stable base to work well, particularly at high magnification. This has a stabilizing bar that gives a more secure feel. The zoom is functional, and it does work out to the highest level. However, due to effects of sun, it can make for an indistinct view. The focus is adjusted in the front part of the body. The zoom is adjusted just under the eyepiece. For the money, it's a great quality scope. It's not a Swarovski or Vortex, but it's good enough for me. I can sight buildings and tractor trailer trucks several miles away. I can see the street conditions a few miles away. The scope works well out to 150 yards. There weren't any targets available at 250 yards. I could see shoot and see hits very distinctly. The biggest and major negative is size and weight. It's bigger than the average more practical scope, but I'm adaptable. I purchased a large carbon fiber tripod for this and it works extremely well. Overall, I'm very pleased. ... show more

The scope arrived in a damaged box, torn case and lens dented in various places. Lens cap would not affix to the scope. Obviously a returned item and maybe even a used item.
