20 inch Starmaster Dobsonian with Zambuto mirror

20 inch f 4.3 Dob with Zambuto mirror (2002).  Scope constructed by the late Bob Kirschenmann for his personal use.  I am assisting Bob’s widow with sale of his astronomy gear.  I own the twin sister to this scope (visible in garage in attached picture) and can attest to stunning performance when Missouri seeing allows and on trips to Okie Tex and WSP. I have observed through this scope of Bob Kirschenmann's and image quality is equal to the one I own. In excellent seeing these scopes will split Sirius, see the six stars in the trapezium and a sprinkling of more 15-16th magnitude stars across the trapezium.  In dark skies I have seen excellent images of Messier and NGC galaxies. Jupiter and Saturn yield stunning detail in good to excellent seeing conditions.  Bob K built the mirror cells for Starmaster (and for this scope).  Scope is too large and heavy to ship.   Options would be pickup in Washington, MO; or meeting somewhere between Illinois and Denver. I make multiple trips to Denver yearly and own a pickup truck with covered bed capable of transporting this scope. Included are shroud and custom built box for mirror in cell. I have several additional pictures that can be sent on request.
