SIGHTRON Infini D50 Refracting Telescope NGA0003

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. The infini D50 is an astronomical telescope set that comes with a refracting telescope tube with an aperture of 50mm and a focal length of 540mm, a Mini AZ mount, an eyepiece, etc. The telescope tube was developed by experienced optical designers at SIGHTRON Japan and is a high-quality achromatic refracting telescope incorporating high-precision lenses made in Japan. Each unit is carefully assembled by craftsmen at our own factory in Tainai City, Niigata Prefecture. The infini D50 is an astronomical telescope that pursues "clear visibility and ease of use," and is designed to be easy to use even for beginners. This is a product that SIGHTRON Japan is proud of, with attention to detail hidden in areas that are not reflected in numerical specifications such as aperture and focal length. ■ Commitment to optical design Although it is an orthodox achromatic lens, the aperture ratio is designed at F10.8 to maximize the lens's characteristics, reducing various aberrations and achieving a sharp image. This is a masterpiece designed by a skilled designer who knows telescopes inside and out, who thoroughly analyzed the path of light inside the telescope tube. ■ Commitment to visibility The lens, which is the heart of an astronomical telescope, is made of high-quality, high-precision lenses made in Japan. A telescope does not simply have good lenses to provide good visibility. The structure and finish inside the telescope tube greatly affect the visibility. Infini D50 is equipped with a carefully matte paint on the inside of the telescope tube and an aperture ring to maximize lens performance. This reduces the diffuse reflection of light inside the telescope tube, known as stray light, and makes it difficult for excess light to enter the eyepiece, allowing you to enjoy high-contrast images. br＞ You can enjoy not only the craters on the moon, but also Jupiter's stripes, the Galilean moons, and Saturn's rings, even though they are small. The infini D50 was developed as an astronomical telescope that is easy to use even for beginners, but it is fully functional as an introductory model. Not only does it have sufficient performance, but the beautiful star images will satisfy even enthusiasts. ■ Commitment to ease of use Normally, astronomical telescopes come with a small telescope for aiming and a finder. However, traditional finders require a certain skill to adjust, so if the finder is not adjusted sufficiently, it can happen that you cannot see the celestial object you want to see through the telescope itself. Therefore, the infini D50's finder is an open-sight type that is easy to use even for beginners and does not require any adjustment. By attaching a low-magnification eyepiece to the telescope and aligning the target celestial object with the two aiming protrusions fixed to the telescope tube, you can introduce the target celestial object into the field of view of the eyepiece. Even if you are using a telescope for the first time, it is easier to use than a traditional finder. In addition, it is equipped with a finder base so that you can use a full-fledged finder. And focusing is important to see the celestial object you want to see clearly. The knob used for focusing is large for a telescope of this class. It is easy to turn and fine-tune, so you can observe comfortably. ■ Mini AZ mount is lightweight and easy to operate It has a simple structure that does not have any frills, so it is small, lightweight, easy to carry, and easy to operate. You can easily take it outdoors and use it. It is a free stop type that does not require loosening or tightening the clamp every time you operate it. The firmness during free rotation can be adjusted. In addition, it is equipped with a full-circle fine adjustment device in the vertical and horizontal directions, so you can track celestial bodies while looking through the telescope. The presence or absence of this fine adjustment device is very important when choosing a mount for an astronomical telescope, and an altazimuth mount equipped with it makes it easy to track celestial bodies and fine-tune the position of celestial bodies in the field of view, making observations much easier than those that are not equipped with it. The tripod has a three-stage structure and can be easily adjusted to a height that is easy to observe. The height can also be adjusted with the center pole. It also comes with a convenient accessory tray where you can place accessories such as eyepieces. ■Accessories The accessories include one eyepiece with a focal length of 10mm and one with a focal length of 23mm, and a zenith mirror. The eyepiece has a large viewing lens and is designed to be easy to look through even for those who are not used to using telescopes. In addition, the apparent field of view is wide, making it suitable for beginners. Its main feature is that it is easy to find elephants. The magnification obtained with the included eyepiece and infini D50 telescope is 54x for 10mm and 23x for 23mm. A zenith mirror is also included, which is useful for observing celestial objects at high altitudes near the zenith. In addition to the included eyepieces, the infini D50 can also be fitted with commercially available American-sized (31.7mm) eyepieces, allowing you to increase the magnification and observe in more detail. In addition, the Sightron Japan original astronomical observation guidebook "Starry Sky Observation" is included to help you enjoy stargazing. This 52-page full-color guidebook contains basic knowledge about astronomical observation and highlights of the starry sky in each season. It will make astronomical observation even more fun. ■Product Specifications ＜infini D50 telescope＞ Aperture: 50mm Focal length: 540mm Aperture ratio: F10.8 Lens: 1 group, 2 elements achromat Telescope length: approx. 515mm Weight: approx. 1.1kg Finder: Open sight type ＜Mini AZ mount＞ Equatorial mount with full-circle fine adjustment device Mini AZ mount + tripod height: approx. 68 to 152cm Mini AZ mount + tripod weight Weight: Approx. 1.8kg ＜Accessories＞ Eyepieces 10mm (54x), 23mm (23x), zenith mirror, instruction manual, stargazing (guidebook) *Cases are not included. *Specifications are subject to change without notice. *There are no plans to sell the telescope tube alone.
