Twenty inch Dob with a hand-figured f/6.5 mirror that was made the old-fashioned way: figuring by hand and star testing, more figuring by hand, another star test, and so on until the star test was perfect. This scope won 2nd place in optical excellence at Stellafane (and no slouch mirror will win there). Heavy-duty construction, 18 point mirrror cell, shroud, Telrad, 4" secondary, 2" R&P focuser, four vane spider. Finder scope and any other accessories in the picture not listed above are not included. This is a big scope, so shipping will not be easy; I am willing to deliver within 200 miles of Philadelphia. Feel free to call or email with any questions. $3,500 for everthing, or $3,000 for the optics and mirror cell.
