Founder Optics Refractors

The FOT series 86 & 106 features 2-element ED APO triplets;
 the Draco 62, a high-performance quintuplet.
Designed by a renowned Japanese optical designer, made in Taiwan.

As experts in optical engineering, we ensure the highest level of quality control through a rigorous series of collimation and Ronchi tests on every unit. Each telescope is shipped with a serialized quality certification card, guaranteeing performance right out of the factory.

Founder Optics is committed to delivering an exceptional user experience. Whether you're capturing deep-sky images or observing visually, you'll notice an exceptionally bright, crystal-clear, and razor-sharp image. With virtually zero aberration, minimal distortion, and high contrast, the view is strikingly realistic to the human eye.

Additionally, a dedicated field flattener is included in the box—complete with both M42 and M48 adapters—to offer seamless compatibility with a wide range of cameras.
