I just bought this on Astromart about 2 months ago. It is the f/4.7 version, focal length 1200mm. I am the 3rd owner, and the scope is less than a year old. I've used it a few times, but my viewing tends to be in 30 minute spurts, so this scope won't get that much use.
This dob is in like new condition optically and cosmetically. The last owner blackened the inside of the tube, so the contrast is better. It comes with the original accessaries:
25mm plossl (I've never had either of these in a scope)
telrad (no finder).
I will ship in the original Orion boxes, and add extra packing. This scope is just like new, and it can be yours for $500 shipped and insured, or $450 locally (pickup).
