iOptron 150 mm Maksutov-Cassegrain OTA - 6101

The iOptron® 150mm Mak is a Maksutov-Cassegrain telescope with a Rumak-style secondary mirror that is perfect for the serious amateur astronomer who wants apochromatic refractor-type performance at an affordable price. In fact, the multicoated and fully-baffled optics provide almost similar results as a 5-inch apochromatic refractor -- at a fraction of the cost.

The MAK150 from iOptron is the only Maksutov-Cassegrain of its kind that comes with a dual speed focuser for fine-tuning your images. Also included is an attachable dew shield—rare for a MAK—for better performance in cold temperatures.
