I have a 13.1 Coulter mirror for sale for $450 and you get the big Odessey 1 tube for free. My landlord put the rocker box in the dumpster by mistake, but one can be built in a few hours. Prefer local San Francisco Bay Area sale. Have to pick up tube this week as I'm moving. Won't ship, too heavy.
The picture is of a sister telescope for size and shape. The box is black and the tube light brown in mine.
