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.

Customer Reviews:

Ultima 100 4" / 100mm Spotting Scope
By Jim
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.

Just what I was looking for
By Jack D
I purchased this scope for multiple reasons. Mostly for using at the shooting range, but also for other uses including as a lens for my camera.
I am extremely pleased with my choice. First use proved that the image is clear and bright even with the low light conditions at dusk.
The test used was to spot targets at 50' & 100'. The scope was then tested at a known distance of 1000'. I could count the kernels of grain on a stalk of wheat at this distance.
I found that the zoom and focus controls operate smoothly.
The performance of this scope and reasonable price are hard to beat.
