Prodott Overview
The Celestron MAK 90mm spotting scope features a Maksutov-Cassegrain optical design, which is known for its compact size and excellent image quality. This design folds the light path, allowing for a much shorter optical tube compared to other scopes of similar focal length, enhancing portability. The scope is equipped with multi-coated optics to maximize light transmission and ensure bright, sharp views.

Operating the Spotting Scope
Iffukar
To achieve a clear image, rotate the focus knob located on the side of the main optical tube until the image appears sharp. For terrestrial viewing, focus on a distant object. For astronomical viewing, focus on a bright star or the Moon.
Terrestri Viewing
The 45° erect image diagonal provides a correctly oriented image, making the scope ideal for observing land-based targets. Use the finderscope to locate your desired object, then look through the main eyepiece and adjust the focus for clarity. The 90mm aperture gathers ample light for bright views even in challenging conditions.
Astronomiku Viewing
While primarily a spotting scope, the Maksutov-Cassegrain design also excels at astronomical observations. Its high magnification and light-gathering capability allow for detailed views of the Moon, planets, and brighter deep-sky objects. For comfortable viewing of objects high in the sky, the angled eyepiece is particularly beneficial.
Digiscoping (Photography)
The C90 spotting scope is designed to be camera adaptable for digiscoping. To capture images through your scope, you will need an optional T-Adapter and a T-Ring specific to your DSLR camera model. Remove the eyepiece and diagonal, then attach the T-Adapter to the scope's visual back and the T-Ring to your camera body. Finally, connect the camera with the T-Ring to the T-Adapter on the scope. This setup allows the scope to function as a powerful telephoto lens.
