A high quality, economical 9x50 finderscope with fully coated lenses and a 5.8° field of view. It comes with a mounting bracket for C8 type telescopes.
Finderscopes are secondary scopes, used to help locate objects in the main telescope. The larger the finderscope, the more you'll see, to an upper limit of 50mm. Units larger than 50mm have too narrow a field of view to be useful. Finderscopes mount onto the main telescope tube and are an invaluable tool in locating objects for viewing.
