Description
Equally suited to observation and astrophotography, the FF90 APO Refractor Telescope from ZWO features a quadruplet air-spaced apochromatic lens system that eliminates the need for a separate field flattener. The quad APO includes one extra-low dispersion element and dramatically reduces chromatic aberration. It also eliminates the need to calculate back focus distance—just attach your camera with one of the four included adapters and you're ready for imaging. The f/6.8 focal ratio and 609mm focal length collect the light needed for long-exposure, deep-sky photography, but add a diagonal with a high-magnification eyepiece and the scope is ideal for planetary observation.
