Vixen Polarie U Polar Telescope Set 35495 PF-LII

[High precision installation of Polarie U with easy operation] This is a set of polar axis telescope PF-LII and Gokubo arm PU. Suitable when high precision is required for polar axis setting, such as when shooting with a telephoto lens. By introducing the North Star and two nearby stars (total of 3 stars) into the designated positions on the built-in scale, you can easily align the polar axis with an accuracy of within 3 arc minutes. (For the Northern Hemisphere. For the Southern Hemisphere, the three stars in the Octant constellation are also used.) [Information collected on the built-in scale, comfortable setting while looking through] Since the built-in scale collects the position information of the stars used for polar axis alignment, the hour angle scale installed on the outside of the conventional polar axis telescope can be easily set. There is no need to read at a dark observation site. You can use it comfortably while looking into the field of view of the polar axis telescope. [Darkfield illumination (with auto-off function)] Built-in darkfield illumination (red LED) that can be easily turned on with a single button. Unlike the bright-field illumination method, which brightens the field of view and allows you to see the scale as a silhouette, the scale itself glows red, so dark stars do not become hidden in the background. The brightness is variable in 8 steps, so you can use it at your desired brightness. Furthermore, since the light automatically turns off (gradually dims) after 1-2 minutes, you can prevent forgetting to turn it off after use. [Equipped with 3/8 inch spare screw holes] The included polar axis telescope arm PU is equipped with two 3/8 inch spare screws, so the 1/4-3/8 inch conversion screw that comes with Polarie U When not in use, screw it in here and store it to prevent it from getting lost.
