<p><span style="font-size:18px"><span style="font-family:times new roman,times,serif">The 5-element 80/100/120/150 ED Super APO Triplet refractors are identical to the triplet ED120 and triplet ED150 refractors, but they have in addition a doublet field flattener lens to get a 44mm diameter flat field without aberration and distortion. Their M48x0.75 adapter for cameras assure larger clear aperture than the classic M42x0.75 adapter (also called T adapter) and thus eliminates any vignetting (loss of light in the edges) on big full frame cameras.</span></span></p> <p><span style="font-size:18px"><span style="font-family:times new roman,times,serif"><strong>Main Features:</strong></span></span></p> <ul> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Premium optical materials</span></span></li> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Short focal length and full frame corrected focal plane</span></span></li> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Excellent field flatness</span></span></li> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Precision linear power focuser is standard</span></span></li> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Metallic high-transmission lens coatings</span></span></li> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Light-baffled optical systems</span></span></li> <li><span style="font-size:18px"><span style="font-family:times new roman,times,serif">Telescope tube attachment hardware</span></span></li> </ul>.
