The TS APO80Q is an 80mm refractor with a focal length of 544mm. In terms of optical construction, it is an apochromatic triplet with an additional two-element field flatness corrector (quintuplet, 5-element system), dedicated to advanced astrophotography of deep sky objects in wide frames and visual observations of planets and the moon. • lens: three-lens APO with FPL-53 glass
• Perfect color correction appropriate for apochromatic construction
• built-in flattener (allows to obtain a flat field even for large CCD matrices)
• 2 inch high-strength cut, teflon washer bearing, millimeter graduation
• system of internal diaphragms that do not generate vignetting also in full-format cameras
