This upgraded model, will absolutely amaze you.The De-Luxe version has a much higher specification: If you are thinking of buying a Maksutov, you may wish to consider the OMC-140. the optics are all hand crafted to achieve a previously unattained performance in a telescope of this aperture. The secret of the telescope's exceptional performance lies in the computer optimised design - no compromises have been taken in the production of this quality product. The majority of Maksutov made today, all have spherical surfaces. Designs utilising all spherical surfaces which use a small section of the reverse side of the corrector as the secondary mirror, cannot and will not produce images as good as an Aspheric system - as in the OMC-140. The reason they are made and left spherical is to enable them to be mass produced on relatively simple polishing machines. In the OMC-140, all surfaces are Laser Interferometer tested and hand figured to achieve excellent image quality. Particular attention is taken with the primary, which has a strong aspheric curve introduced by skilled opticians in the workshop.The manufacturers believe they have designed and built a telescope to optically out-perform absolutely anything of comparable design, anywhere in the world. The Baffle System is an extremely important factor in the telescope's design. If any stray light - reflected or refracted - is passed to the telescope's image, the contrast of the image suffers greatly. The obvious result of this is a visible white haze around objects being viewed. The optical technicians producing the corrector plates, test each surface over 10 times with a Zygo interferometer to achieve a surface accuracy of better than 1/16th wave peak to valley. Other features include, 31.7mm optical back for eyepieces, Industry standard dovetail attachment plate, Micrometer focusing, Collimatable system for precise optical performance.
The innovative STAR BOOK hand controller offers astronomical navigation with a large full-colour LCD screen! The colour screen is a detailed star chart that acts as a navigational and GOTO guide for the mount. It's features include: Large colour liquid crystal display. (4.7 inch, 320x420 pixels, 4096 colours)
With the STAR BOOK (Star-Chart Go-To Controller) You can simply aim a telescope, mounted on the SPHINX, at any celestial object by clicking on the LCD panel. The LCD panel offers a a comfortable 4.7-inch screen (320X240 pixels) with 4096 colours. The STAR BOOK comprises of an ultra-high-speed CPU internally which is an 32bit RISC processor, CS89712 (ARM720T Core), 75MHz clock-speed with 8MB SDRAM and 4MB Flash ROM. ((L)195mmx(W)145mmx(H)28mm.
