Lens construction: 2 elements (fully multi-coated) Screw diameter: 28.5mm Screw pitch: 0.6mm Frame thickness: 7.5mm Standard back focus: 37.5mm - By attaching it to the nosepiece of an astronomical CMOS camera, you can capture a wider area. *Suitable for use with telescopes with an F-number of 10 or higher. American-sized filters (screw pitch: 0.6mm) can also be attached. In addition to photography, it can also be used by attaching it to an eyepiece. ・Manufactured at Sightron Japan's Niigata Tainai Plant. *This product is designed to be attached to refracting telescopes with an F-number of 10 or higher. Using it with an optical system brighter than F-number 10 will increase spherical aberration. *Depending on the optical system, it may not be possible to focus at infinity. *The magnification will change when the back focus of the lens changes. Also, the further away from the standard value (37.5mm), the more likely the performance will decrease.
