I guess the economic situation is slowing down sales, so I've reduced the price to $550 + actual shipping charges CONUS -- less than 70 percent of new price and you don't have to wait.
Here's the orginal ad:
Like new, Optically certified Intes-56 5-inch F/6 Maksutov-Newtonian
You can still have the equivalent of a 5-inch APO refractor for a few hundred dollars – AND STILL IN TIME FOR MARS!
SPECIFICATIONS (certified by a Florida optical laboratory and ITE telescope)
Serial no. 2.905
Wavefront Error (p.t.v.) 1/7.4 wave at 555 nm
Strehl ratio: 97.4 %
Resolution (on-axis) 0.89 arc seconds
Resolution (½ degree off axis) : 0.89 arc seconds
Image spot size (on axis) 8.2 microns
That is considerably better than diffraction limited, which is defined as at least 1/4 wave or better with a Strehl ratio greater than 80 %
Comes with carrying case and newer focuser.
I also have a GM8 saddle and universal dovetail to go with the mount. Let's talk. I have too many scopes. --rb
