iOptron 150mm Maksutov Cassegrain OTA

The iOptron 150mm Maksutov Cassegrain OTA is an exceptional choice for serious amateur astronomers seeking apochromatic performance at a much more accessible price point. This 6" Rumak-type Mak-Cass optical tube delivers impressively sharp and contrast-rich images, rivaling more expensive 5-inch apochromatic refractors.

Its long focal length (1800mm, f/12) is ideal for high-magnification views of planets like Saturn and Jupiter, while remaining light and portable enough for backyard and field use. Its multi-coated optics enhance clarity and reduce chromatic aberration, delivering vibrant images of celestial objects.

Unique among Maksutov designs, this model includes a dual-speed focuser for fine-tuning sharpness, and a twist-lock aluminum dew shield that minimizes dew formation in colder climates. Whether for lunar observation or planetary imaging, the iOptron 150mm Maksutov delivers reliable, high-quality performance.
