180 f/1800 Maksutov-Cassegrain

One of the exciting new products from STF is a 7.1" f/10 MCT.

APM-Telescopes and STF are pleased to announce the start of joint production of a telescope similar in class and design to the INTES MK66. The 7MK f/10 is a scaled up version, with an adjustable main mirror. Otherwise identical to the INTES (the same mechanical design, paint, and finder, and possessing the same, or even better optical quality), yet with some advantages over the INTES. Its spherical optics have a stable oxide multicoating. We decided to make the 7MK f/10 to a minimum quality of 1/6 wave front. Each scope has a serial number and interferometrical test images to prove its quality.

Technical Specifications:
• Aperture 180mm / 7.1 inch
• Focal length: 1800mm / 71 inch
• F-ratio: f/10 - max. field of view: 1° 20'
• Minimum wave front quality: 1/6 or better
• Finder scope: 10 x 50
• Tube length with dewcap: 690mm/ 27.16 inch
• Tube diameter 208mm / 8.2 inch

• Mounting plate on bottom with 1/4-20" and 3/8" threads
• Knife edge baffle in dewcap
• Covers on all optics
• Spherical mirrors made from Pyrex, stable coating provides 96% reflection
• Meniscus lens made from Russian analogue of BK7, multicoated
• Adjustable mirror focuser with zero image shift
• 2" Schmidt-Cassegrain thread for multi-purpose use
• Back focus allows use of a binocular attachment with this scope
