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.

PRICE: $635 + shipping CONUS, or less than 80 percent the cost of a new unit and shipped immediately upon payment. (It generally takes about two to three weeks to get a new scope from ITE.)
