famous PHD Astro-Physics Philipp Keller/Germany designed us a coma free 275 mm F/14 Maksutov Cassegrain Optics with 25 % central obstrction, large backfocuse and slighly figured spherical system.
The mirrors are made from high qualityx USA Quarz 8 shipped to Russia for polishing)
the Optical set will be supplied with a very light weight , very fast cooling down tube , made by famous Matthias Wirth in germany.
The telescope will get a fast secondary focuse, a high quality starlight focuser, cooling fans, a meniscus anti-dew heater
the specsof the quality ordered will be confirmed by a interferometrical testreport and they are:
1/10 wavefront p.t.v.
1/50 wavefront RMS
98.4 % strehl
delivery of the optics is planned for January 2014, the complete OTA shortly after
the final price is not fixed yet, depends on all features we install into the tubes and the exchange ratio, but it will be roughly around 20,000 to 25,000 US $
