I have decided to sell my 10 f10 planetary Newtonian.  Before I list it on another site I thought I'd give the Utah folks a chance.  Here are some of the details: Primary mirror diameter 10"Primary focal length 97"Primary mirror is Astro Sital zero expansion ceramicPrimary mirror fabricated by Intermountain opticsSecondary mirror minor diameter 0.875"Secondary mirror is PyrexThere is NO spiderSecondary mirror is mounted to an optical windowOptical window is 12" diameter BK7 optical glassOptical window is ground and polished flat and surfaces parallelOptical window fabricated by Intermountain OpticsTube is 12" diameter 0.125' thick aluminumTube is cork lined and painted flat blackTube is painted with Imron paintMirror cell is all anodized aluminum Mirror cell collimation is push-pull typeMirror cell has built in 12 volt fan for coolingOptical window cell is anodized aluminumSecondary mount allows full collimation capabilityTube includes detachable 24 inch cork lined forward light baffleIncludes cradle which allows 360 degree tube rotationTelescope includes an 80mm right angle Lumicon SuperfinderFocuser is an Astrosystems low profile Crayford focuserAlso includes a Telrad The optics in this scope are excellent, and allow excellent refractor-like high power views of the moon and planets.  Since it is also a 10 inch telescope and allows deep sky viewing equal to or better than any other ten inch telescope. I am not sure what the value f this scope is, but I believe $4,500 is a fair price. Any interest? Brent Watson
