Takahashi FSQ-130ED Super APO Imaging Refractor - OTA

The Takahashi FSQ130ED is the ultimate astrograph. A quintuplet super-low dispersion optical design which uses specialized anti-reflection coatings to transmit the the maximum light to your camera sensor. It's also the perfect image travelling companion! At only 22" long and very lightweight, it is easily supported by a medium-duty mount. 175mm of back focus allow for easy adaptation of long focus imaging set-ups.

Staying true to Takahashi's legendary and supreme optical designs, the FSQ130 produces a perfectly flat-field. By utilizing a five element design which incorporates 3 ED elements made from premium optical glass, color, brightness and contrast are at their very best. When used at prime focus, you'll enjoy a 110mm image circle with pinpoint sharp stars from edge to edge with 92% illumination.

Included with the FSQ 130 APO optical tube is a 5" focuser capable of heavy-duty work loads. Your heavyweight imaging set up is in safe hands. Integrated is a camera angle adjuster and rotator for optimal camera sensor placement.
