The Celestron Ultima series was designed to perform well in a range of viewing situations, making it a great all-around optical instrument. You’ll love it for observing nature and long distance spotting and since it is completely waterproof you can feel comfortable using it in extreme weather. The green rubber optical tube allows for subtle observation in any environment. Ultima spotters are a great companion for any nature or outdoor enthusiast.
The Ultima 80a zoom eyepiece has a standard camera adapter thread (M42) built in allowing you to easily attach a DSLR or mirrorless camera into a high powered telephoto lens. Just use an appropriate T-ring for your digital camera (sold separately).
Soft carrying case included.
