Celestron Ultima 100 Overview

Celestron manufactures the Ultima line of Prismatic Spotting Scopes in 65mm, 80mm, and 100mm varietals to suit your needs. All the Ultima line are mated to an eyepiece and render views that 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-through 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 among 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 among 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 scope (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.

Built-In T-Mount Threading for SLR Shooting
The Celestron Ultima series feature a T-mount threading upon the eyepiece barrel, allowing your scope to act as an ultra-telephoto lens upon your SLR camera (digital or film) with just the addition of a camera-specific T-mount adapter.

question

Are there any extenders or eyepieces for increasing the magnification? Scope is just OK at 200 yards and would like something to see targets at 300 yards; less than an inch.
Asked by: Anonymous
I would steer clear of anything that give you "more power." One would need a larger objective lens to accomplish what you are desiring. Otherwise, an increase in power will only give you a larger image, but it's ultimate clarity (resolution) will not get better with the image only getting fuzzy.

question

I have a canon T3i. Can I take clear pictures through this scope? What is the B&H part number to attach the T3i?
Asked by: Anonymous
All you would need to mount your Canon T3i onto this Spotting Scope is a T-Mount Adapter. You could do the Vello Lens Mount Adapter- T-Mount Lens to Canon EOS Camera. What you will do is peel the eyecup part of the scope off, and the T-Adapter Ring will thread onto the top of the Eyepiece where the Eyecup was. Then you can mount your camera onto that ring.

What do I need to attach a Sony E mount to a Celestron Ultima 100 or 80? Thank you
Asked by: Rolando
Hello Rolando, thank you for your inquiry. Sony T-ring adapters are available for the Sony E mount. Check with B&H Photo. With such an adapter, all Celestron scopes that accept T-ring connections should be compatible.

question

Can this scope be attached to a Pentax K10?
Asked by: Anonymous
Yes you can attach your Pentax K10 onto this scope, you would just need a T-Ring Adapter to attach your body. The eyepiece part of the scope peels off then there is a threading that the T-Ring threads on to. The T-Ring you could get is the Vello T Mount Lens to Pentax K Camera Adapter.

question

Does it come with Tripod mounting adaptor ? if not what adaptor is suitable for this scope?
Asked by: JAYANTA B.
Yes it does, in fact, it comes with a sliding rail mount that allows you to position the scope so that it is balanced for whatever eyepiece you may be using. The fasteners are all 1/4-20 which is industry standard and will fit your tripod.

question

What do I need to attach a Nikon D5100 to a Celestron Ultima 80 or 100?
Asked by: Anonymous
This scope is about on the limit for magnification but i have tried the Nikon T-Mount (available at B&H) attachment with a D90 and it connected successfully. I could not recommend connecting a camera to this scope as the results were awful. It did not matter what changes to the camera settings i made i could not get any acceptable results. A different scope may yield better results but i have doubts.
