I have a 12.5 F6 Newtonian OTA for sale. The primary mirror is a Wilkerson
Galixy mirror, tested to 1/16 wave with a Strehl ratio of .963. Recent coatings
were at 96% reflectivity. 2.15 inch secondary, 1/20 wave, mounted on
a curved vane spider. Contrast is exceptional, with no diffraction
spikes present when viewing stars. Crayford focuser, University optics
50MM right angle finder, and electric focuser included. Tube is 16inch
parks type with rotating ring assembly. Pick up preferred.

$1200 or best offer.(but be realistic)
Best to phone 561 369 5120 after 8 pm, anytime on weekends
