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. The Alter M615 has a longer focal length and focal ratio (F/15) than the 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.
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.
Focusing is achieved by moving primary mirror (with zero image shift). Standard 2" outer thread for connection of adapters and accessories from other manufacturers. Telescope OTA 100% metal construction - painted cream-white - with computer-optimised knife-edge internal baffling for maximum image contrast.
System optical quality minimum 1/6th Wavefront p.t.v. with High Transmission coatings on all optical surfaces, the Mirror surfaces have 95% reflectivity and the Meniscus lens is also multi-coated. Dovetail rail (Vixen/Synta type) & Mounting Plate with 3/8" threaded holes. EQ5 Equatorial Mount or Higher, recommended. Supplied with Transportation Handle & Protective Carrying Case.
