The iOptron Rumak-type 152mm Maksutov-Cassegrain is perfect for the serious amateur astronomer who wants apochromatic refractor-type performance at an affordable price. In fact, the multicoated optics provide almost similar results as a 5-inch apochromatic refractor -at a fraction of the cost. You will be amazed at the images you'll see with the MAK 152mm-surprisingly, an f12.5 that can view Jupiter's cloud bands and also M31.
The precision design and engineering of the optics produces images you would not expect in such a light tube. The MAK 152mm from iOptron is the only MAK 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.
