Top Features:

So, what does this spotting scope offer? Here is a look at some of the top features that you would love about it.

Large Aperture

Spotting animals or birds around dusk or stargazing at night can prove to be a tough task since there is not enough natural light to assist you. The 100 mm range of Celestron Ultima Zoom lenses with a 4” diameter, offers a large aperture that can be adjusted according to your light requirements. At its maximum, it allows plenty of light in, which makes viewing in low-light conditions easy with no compromise on the image quality.

Water Proof

Rain or humidity does not keep nature from springing a rare sighting and neither should it hold you back. If your lens shies away from water, you might have to miss that exotic bird that flies out in the rain. However, the Celestron 100mm Ultima Zoom lens has you covered, as it is waterproof and functions optimally in damp and humid conditions or when it is pouring so that weather does not water down your spotting adventure.

45-Degree Viewing Angle

This range from Celestron comes with an additional angled viewing scope, other than the standard straight viewing scope. From an angled view, spotting or taking photographs of objects at a height becomes easier, without having to strain your neck unnaturally. It also enables users with varying heights to use the lens simultaneously, without the hassle of readjustment.

22-66X Zoom Eyepiece

The lens has an excellent 22-66X zoom capacity, which can make all the difference during bird sighting or shooting at long ranges. It keeps the image quality intact throughout the zoom range, providing you sharp picture results. The range of sight gets substantially enhanced which makes it a great equipment for sky watching and stargazing as well.

Built-in T-Mount Threading

Celestron 100mm Spotting Scope also provides you the option to use the zoom scope as a telephoto lens for your camera. By attaching a T-mount adapter suited to your camera, you can use the scope as a lens with enhanced zooming capacity to focus on faraway objects from a safe distance. This allows you to take pictures of subjects in their most natural environment. The 45-degree angled view also enhances your field of sight.


  • Comes with a carrying case, which makes storage and transport easier.
  • 45-degree viewing angle enhances the range of sight.
  • Green coloured optical tube provides camouflage in natural environments to enable subtle viewing.
  • Optical tube is rubber coated to provide comfortable handling and shock absorption in case of impact.


  • At 7 pounds, the lens alone is rather bulky. Team it with a sturdy tripod to support it and it becomes quite a task to lug it around.
  • The case included with the lens it easy to carry but is made of plastic and not very durable.
  • There may be some image distortion towards the 60+X of the zoom.
