7"F/8 ( 180F/1440) Maksutov Newtonian. This is the newest version of INTES MICRO Telescopes, a Maksutov Newtonian with only 13.4 % central obstruction , small enough to show not anymore any diffrence to a same size colorfree apochromat. Field of view is enough for 1.25" eyepieces, backfocuse is enough to use CCD Cameras with smaller sizes chips. The scope comes in cremewhite paint and 2" focuser with extensions and adapter 1.25". At the rear of primary mirror cell is attached a 12 volt colling fan and the cell of meniscuslens is holespaced for ctive cooling too. The tuberings have on top a guidingscope mount plate and on bottom as standart a Losmandy G11 rail ( other rails are possible). I think , no other catadioptric telescope can come closer to an real apochromat in contrast and performance.
