 Takahashi TOA-150 The TOA-150 is the second Ortho Apochromat to be developed by Takahashi. It features a newly designed triplet objective, which, like its smaller companion the TOA-130, is absolutely colour free. The 179mm oversized tube is used to provide superior baffling and extremely high contrast. Knife-edge baffles inside the tube help provide this great contrast. The high contrast and total lack of colour makes the TOA-150 not only an outstanding optical instrument, but it can be used to make outstanding images with a CCD, digital SLR or film camera. Framing the image or placing the eyepiece in a convenient position is made simple by the built-in camera angle adjuster that allows 360-degree rotation of the camera or eyepiece without loss of focus. The smooth heavy-duty retractable lens shade allows the length of the TOA-150 to be reduced to 38 inches for easy transport to remote sites. Attaching the Extender TOA converts the 150 into an f/11.68 planetary instrument capable of very high magnification images. It maintains the colour correction and flattens the field. |
