Takahashi TOA Telescopes are the first of Takahashi's newest optical design: The Ortho-Apochromat. This 21st century innovation employs a newly designed triplet using special elements to produce the highest order of color correction and is packaged in a short 32" tube with the lens shade retracted. It includes a deluxe 4" focuser with built in camera angle adjuster. The camera angle adjuster enables the observer or astrophotographer to turn the ocular or camera 360 degrees to better view or frame an object to be photographed. The 4" focuser, coupled with the optional dedicated flattener, will produce a fully illuminated 70mm circle with a usable 92mm diameter. The high order of color correction of the Ortho-Apochromat Series produces images with saturated color and, thanks to the numerous knife-edged baffles, it also displays an image with amazing contrast.
