I purchased this 17.5 inch set-up , but have had little time to use it. To heavy for me plus divorce and subsequent move forces sale!! O.D. of tube is 20". A second, and much longer unaltered tube (to act as a better dew shield) is included in price as are 40mm,32mm,25mm,20mm,15mm,9mm,6mm, and 4mm
Plossels, (two) 2x Barlows, seven various filters, Celestron ocular case with locks and keys,, two extra focusers (1' and 2'), two tube end caps , the old Coulter-style (wood) mirror cell that was replaced by the previous owner as well as a battery powered fan to aclimate the large Pyrex (according to Swayze its not just glass) mirror to its ambient surroundings. Two finders including Telrad and Orion 9x50. Tube is thick and painted white (looks pretty good and clean, but some marks) and alt-azimuth is OSB wood painted black in fair condition. ALSO included in price is a 6" f8 old (20 years+) Criterion style RV-6 telescope with clock drive, metal mount, etc. One tube ring needs repair, and some rust is evident in spots with smakll holes in tube); mirror may or may not need recoating. Its been sitting unused for a while, and needs a new home ! First photo is a few years old, and their has been some updating and maintenance to both telescopes since that photo. Think of the 6 inch as a freebie! Make an offer!!
