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

Ultima series scopes feature multi-coated optics to provide exceptional clarity and brilliance. All Ultimas are waterproof, making them more robust than ever before. They perform extremely well under all light conditions which makes them ideal for all types of outdoor viewing activities including bird watching, nature and wildlife, target shooting - even astronomy.

The Ultima series now offers the choice between 45° angled viewing or straight viewing. 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.

Built-In T-Mount Threading for SLR Shooting
The scope features a T-mount threading on the eyepiece barrel. This allows it to function as an ultra-telephoto lens with your SLR camera (digital OR film), with just the addition of a camera-specific T-mount adapter.

              Comments about Celestron Ultima 100 4"/100mm Waterproof Spotting Scope (Straight Viewing) Kit:

              Chose this Canadian scope over an Italian Brand. I read a lot of reviews. It was to replace a cheap chinese scope (Saxon) that I was using. The scope arrived - works well but was not as good as I had expected after the reviews I had read. An it is still MADE IN CHINA.

              I would like to physically compare scopes - because this is not an objective review. I am a photographer - used to looking through ED Glass - so it is a toy compared to those optics and priced accordingly.

              Its Line Pair resolution is good at wide to mid magnification and declines at 55+. Flare increases with magnification. Either way I am enjoying using it with the children - stress free.

              Comments about Celestron Ultima 100 4"/100mm Waterproof Spotting Scope (Straight Viewing) Kit:

              I'm using it for a month now.
              I'm enjoying nature watch and digi scoping with it.
              Before I buy this one, I had Regal 100.
              I expected Regal 100 is much better than Ultima 100 but I couldn't find any big differences with my eye and Cannon 50D.

              Picture was great with max zoon than I expected.

              I'm planning to buy 105mm circular polarized filter for better picture images in daytime.

                  Very good view and zoom.
                  Dificult to balance on a tripod.
                  Focus controls very sensitive.

                          This is great for spotting, and astronomy especially the moon. You can actually see the craters on the moon and widlife spotting almost puts you right next to the animal from hundreds of yards away.
