INTES MICRO

INTES-MICRO of Moscow are specialist manufacturers of Maksutov-Cassegrain and Maksutov-Newtonian astronomical telescopes, which are aimed at advanced astronomers seeking the highest standards of equipment available. These telescopes are individually and painstakingly handcrafted by highly skilled optical technicians to extremely strict optical and mechanical tolerances, and have gained an outstanding reputation amongst the specialist astronomical community for offering a range of professional quality products, providing high-performance, high-contrast, high-resolution imaging for astrophotography and visual (deep-sky and planetary) applications. The Maksutov-Cassegrain models excel for high power, high resolution Lunar and Planetary work. Their compact tubes make them particularly convenient to transport and set up.The Maksutov-Newtonian design combines the best features from a Newtonian Reflector and a Maksutov-Cassegrain to create a telescope design that provides truly stunning image quality, similar to those achieved with Apochromatic refractors, but at a fraction of the cost.

INTES-MICRO ALTER M615 6" 152mm

!

6" F/15 SS Maksutov-Cassegrain optical system with moving primary mirror focusing.

The Alter M615 has the longer focal length and focal ratio (F/15) than Alter M603 which makes it to be a small portable lunar and planetary instrument. Due to a smaller central obstruction it provides low level contrast in the images which makes it better for visual observation.
