请看简介
The FS-152 is the newest addition to the Takahashi© fluorite apochromatic FS-Series. It has been designed with the serious observer or astrophotographer in mind.
The 4" focuser is standard with a 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. In order to optimize the photo/visual use of the FS-152, a special f/5.9 reducer and f/8.1 field flattener have been designed. The custom reducer produces a 65mm circle, 4.1" across, on medium format film while the flattener will produce an incredible image circle of 90mm.
The standard EM-200 or optional NJP mounts provide a stable, accurate platform for the FS-152. The integral polar alignment telescope and R.A. axis level make accurate polar alignment to within 2 arc minutes of the celestial pole quick and easy. The reticle is designed to be used in either Hemisphere until the year 2030. No other manufacturer uses such a highly accurate polar telescope.
