This is a custom high quality achromatic refractor made by David Hawkins. The lens is a 152mm f/7.9 (focal length 1200mm) APM/TMB lens. I can give further details about the lens privately. The glass is of higher quality than the standard 6 inch f/8 achromats, with SMC multicoating and better figure and lens cell. The aluminum tube was made by Parallax Instruments and professionally painted, with sliding dew shield. The focuser is a 2.7 inch Astro-Physics single speed model. The scope comes with matching Parallax rings. The optics are in excellent shape with very little dust, and the cosmetic condition is excellent. There is a minor scrape on the lens cell (not the lens) that was present when I received the scope.

The views through the scope are beautiful. I have looked through several 6 inch f/8 achromatic scopes that had to be stopped down due to turned edges or other aberrations. You can view full aperture in this scope. Focusing is a joy. Of course, the scope still has chromatic aberration, and the best views of planets will be with a filter. The scope was to be used for outreach with a Chromacor, but my plans changed and that is why the scope is for sale.

The price is $1100 for the scope and rings (mount not included). Local pickup is great, or add $150 toward shipping in the US (this is a big scope). If you want the C160 Stellarvue case (no longer made), then add $125.
