The A105M Achromatic Refractor Telescope is a simple to use and high power refractor great for beginners who still want a high performance telescope. The lens of this scope is made up of convex crown glass and concave flint glass elements that are combined smoothly to reduce chromatic aberration while also enhancing clarity, before then being coated in a Magensium Flouride compound to further refine the optical quality and durability. Light transmission is maximized by these coatings, while the optical glass itself has been designed to make optimal use of that increased light transmission. The end result is pinpoint sharp star images and clear views of any object in our solar system, from our own moon to Jupiter! This precision instrument is manufactured in Japan.
