Vixen Astronomical Telescope Accessories Telescope Finder Darkfield Finder II 7x 50mm 86161-3

---------------------------------------------------------------------- [Small telescope that supports the introduction of astronomical objects] This is a finder for astronomical telescopes with a diameter of 50 mm. The low magnification of 7x provides a wide field of view, making it easy to capture the target celestial object in your field of view. By placing the desired celestial object on the built-in scale (crosshair), you can introduce the celestial object into the field of view of the astronomical telescope. [Good visibility even in the dark night sky! With dark field illumination: Dark field illumination (red LED) is built into the scale (crosshair), so you won't lose sight of the scale even at night when the background is dark. The brightness of the lighting is variable, so you can use it at your desired brightness. The center part of the crosshair is open, which prevents the star from overlapping the line and making it invisible, allowing you to align the star firmly in the center. [Eyepiece unit can be attached and detached (31.7mm) *1] The eyepiece unit is a removable plug-in type (31.7mm diameter), so a 31.7mm plug-in CMOS camera (commercially available) *2 can be attached and used as a guide mirror. *3 *1 Even if you remove the eyepiece unit (eyepiece with cross scale) and attach the separately sold 31.7mm diameter eyepiece, it will not focus, so you cannot use the separately sold eyepiece. *2 As a guide, the model is designed to be compatible with CMOS cameras with a distance of approximately 17 mm from the bottom end of the 31.7 mm sleeve on the camera side (the constricted part where the thickness changes) to the sensor surface (on the opposite side from the sleeve). The focus position may differ depending on the camera you are using, so please make your own adjustments, including how to install the CMOS camera and adjust the focus on the viewfinder. Please also read the instruction manual for the finder and the CMOS camera you are using. (If you adjust the focus of the finder (= move the focus position of the objective lens), you will need to readjust the focus position when using the eyepiece unit.) *3 If you use it as a guide mirror, it will be more fixed. We recommend using it with the "50mm finder leg S" (sold separately). Accessories: button battery CR2032 x 1 (monitor battery included) Battery duration: Approximately 48 hours (at 20°C. Continuous lighting at maximum light intensity) 1 year warranty
