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.

Comments about Celestron Ultima 100 4.0"/100mm Spotting Scope Kit:
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 4.0"/100mm Spotting Scope Kit:
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.

Comments about Celestron Ultima 100 4.0"/100mm Spotting Scope Kit:
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 4.0"/100mm Spotting Scope Kit:
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
