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.
